Clamp meter (Tang Meter Digital) merupakan alat yang praktis untuk mengukur suatu aliran arus listrik tanpa harus memutus jalur arus listrik tersebut. Clamp meter atau Tang Amper / ampere memiliki kegunaan lain selain berfungsi untuk mengukur arus listrik tang ampere juga dapat digunakan untuk mengukur voltase atau mengukur nilai tahanan dan resistor. Sangat peraktis dan hasilnya sangat akurat karena di tampilkan pada layar, biasanya clamp meter memiliki layar sebagai outputnya.
NOTE : pengukuran arus di atas menunjukan bahwa angka (-) minus 35,3 Ampere karena arah pengukuran yang tidak benar.
Agar angka menjadi positive caranya mudah, anda hanya perlu membalik posisi clamp meter. Dan apabila sudah stabil angkanya dan anda ingin kunci, anda hanaya tinggal menekan tombol ON/OFF nya saja, sangat peraktis bukan? Tidak perlu memotong kabelnya terlebih dahulu. Cukup menjepit dengan kedua capit clamp meter.

The equipment is protected throughout by double insulation or reinforced insulation.
A WARNING
To avoid possible electric shock or personal injury, follow these guidelines:
• Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors.
• Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged test leads before you use the meter.
• Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced.
• Do not operate the meter around explosive gas, vapor, or dust.
• To avoid damages to the instrument, do not exceed the maximum limits of the input values shown on the meter.
• Before use, verify the meter's operation by measuring a known voltage.
• When servicing the meter, use only specified replacement parts.
• Use with caution when working above 30V AC RMS, 42V peak, or 60V DC. Such voltages pose a shock hazard.
• When using the probes, keep your fingers behind the finger guards on the probes.
• Connect the common test lead before you connect the live test lead. When you disconnect test leads, disconnect the live test lead first.
• Remove the test leads from the meter before you open the battery door.
• Do not operate the meter with the battery door or portions of the
2
cover removed or loosened.
• To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the low battery indicator (" ") appears.
• When an input terminal is connected to dangerous live potential it is to be noted that this potential at all other terminals can occur!
• After you press the Data Hold button to enter Data Hold mode, caution must be used because hazardous voltage may be present.
• CATII-Measurement Category II is for measurements
performed on circuits directly connected to low voltage installation. (Examples are measurements on household appliances, portable tools and similar equipments.) Do not use the meter for measurements within Measurement Categories III and IV.
C A U T I O N
To avoid possible damage to the meter or to the equipment under test, follow these guidelines:
• Disconnect circuit power and discharge all capacitors before testing resistance, insulation resistance, continuity or diode.
• Use the proper terminals, function, and range for your easurements.
• Never measure current while the test leads are inserted into the input jacks.
• Before rotating the range switch to change functions, disconnect test leads from the circuit under test.
• Remove test leads from the meter before opening the meter case.

OPERATING INSTRUCTIO N
AC C u r r e n t M e a s u r e m e n t
1. Make sure the "Data Hold" switch is not pressed .
2. Set the Function/Rang e switch to the desired ACA range.
3. Press the trigge r to open the transforme r jaws and clamp one conducto r only. It is impossibl e to make measurement s when two or three conductor s are clampe d at the same time.
4. The value displayed on the LCD is the AC curren t flowing throug h the conductor .
Insulatio n R e s i s t a n c e T e s t
1. Set the rotar y switch of the clamp meter to the 2000M Ω range.
In this condition , it is normal that the reading is unstable .
2. Insert the three banana plugs V/Q, COM, EXT of the insulation teste r unit to the correspondin g V/Q, COM, EXT input jacks on the clamp meter .
3. Set the range switch of the insulatio n teste r unit to the 2000M Ω
position .
4. Connect the test leads fro m the insulatio n teste r unit to the applianc e to be tested .
5. Set the insulatio n teste r Power switch to the "ON" position .
6. Push the " 500V" button , the red LED "500V" will light. The
readin g on the LCD of the clamp meter is the insulation resistanc e value; if the reading is below 19MΩ, set the rotar y switch of the
the clamp meter and the range switch of the insulatio n teste r unit to 20MΩ range positio n to increase the measuremen t accuracy .
7. If the insulation tester unit is not used, the power switch must set to OFF position. And the test leads must be removed from the input jacks; this can extend the battery life and prevent electrical shock hazard.
D C V o l t a g e M e a s u r e m e n t
1. Connect the red test lead to the "V/Ω " jack and the black test lead to the "COM" jack.
2. Set the rotary switch to the desired DCV range. If the voltage to be measured is not known beforehand, set the range switch to the highest range and then turn down range by range until satisfactory resolution is obtained.
3. Connect the test leads to the source or load to be measured.
4. Read the voltage value displayed on the LCD along with the polarity of the red test lead.
A C V o l t a g e M e a s u r e m e n t
1. Connect the red test lead to the "V/Ω " jack and the black test lead to the "COM" jack.
2. Set the rotary switch to the desired ACV range. If the voltage to be measured is not known beforehand, set the range switch to the highest range and then turn down range by range until satisfactory resolution is obtained.
3. Connect the test leads to the source or load to be measured.
4. Read the voltage value displayed on the LCD.
Resistanc e Measuremen t
1. Connect the red test lead to the "V/Ω" jack and the black test lead to the "COM" jack.
2. Set the rotar y switc h to the desire d Ω. range .
3. Connec t the test leads to the resisto r to be measure d and read the value displaye d on the LCD.
Note :
For resistanc e about 1 Mf i and above, the meter may take a few second s to stabilize. This is normal for high resistanc e readings .
Diod e Test
1. Connect the red test lead to the "V/Ω" jack and the black test lead to the "COM" jack. (The polarit y of the red test lead is positive"+". )
2. Set the rotar y switch to range.
3. Connect the red test lead to the anode of the diod e to be teste d and the black test lead to the cathod e of the diode. The approximat e forwar d voltage drop of the diod e will be displayed on the LCD.
If the connectio n is reversed , only figur e " 1 " will be shown.
A u d i b l e Continui t y T e s t
1. Connect the red test lead to the "V/Ω" jack and the black test lead to the "COM" jack.
2. Set the rotary switch to range.
3. Connect the test leads to the two terminals of the circuit to be tested. If the resistance Is less than about 50Ω, the built-in buzzer will sound.
T emp erat u r e M e a s u r e m e n t
Note
To avoid possible damage to the meter or other equipment, remember that while the meter is rated for 0°C to +750°C and 32°F to 1382°F, the K Type Thermocouple provided with the meter is rated to
250°C. For temperatures out of that range, use a higher rated thermocouple.
The K Type Thermocouple provided with the meter is a present, it is not professional and can only be used for non-critical reference measurements.
For accurate measurements, use a professional thermocouple.
1. Connect the K type thermocouple to the corresponding measurement socket.
2. Set the rotary switch to the desired temperature range.
3. Touch the K type thermocouple to the object to be measured.
4. Wait a while, read the temperature value displayed on the LCD.
Frequenc y Measuremen t
1. Connect the red test lead to the "V/Ω" jack and the black test lead to the "COM" jack.
2. Set the rotar y switch to the frequenc y (2kHz) range .
Connec t the test leads to the sourc e or load to be measured .
3. Read the frequenc y value displayed on the LCD.
M A I N T E N A N C E
• Befor e openin g the case, always disconnec t the test leads from all live circuits .
• Periodicall y wipe the case with a damp clot h and mild detergent .
Do not use abrasives or solvents.
BATTERY R E P L A C E M E N T
When the symbol " " appear s on the display, it shows that the batter y should be replaced . To replac e the battery , open the
batter y door , replac e the exhausted batter y with a new one of the same type, reinstal l the batter y door . Some model s of this series use screws for fastenin g the door , please install the screws.
