a. Do not apply more than 250V RMS to the input.
Current Measurement (with Clamp attachment)
1. To measure current with a clamp, use either a clamp specifically made for DC current or
AC current.
2. Connect the negative output lead of the clamp to the COM Jack and the positive output
lead to the INPUT Jack.
3. Set the function switch to “ ” range.
4. Clamp the circuit to be measured with the clamp.
5. The results will be displayed on the LCD display.
Note:
a. Each time a measurement is taken, make sure that only one cable is clamped and is in
the center of the clamp jaws.
b. The clamp can only test for up to 600A, do not test circuits higher than 600A.
c. Do not touch the circuit with hand or skin.
d. The multimeter assumes a clamp has a sensitivity of 1A/1mV. The indicated value is the
same as the measured value for clamps with 1A/1mV.
i. If you use a clamp whose sensitivity does not equal 1mV/1A, multiply the present
reading by a factor which is determined by the used clamp, the result is the
measured value. To determine the factor, please refer to the instructions of the
clamp which you use.
Auto Power Off
The meter will power off after approximately 15 minutes of inactivity. To turn it on again, turn the
rotary function switch, or press the “Select” or “Range” button for more than 2 seconds.
Battery Replacement
If the “ ” symbol appears on the display, the battery should be replaced immediately. Remove
the rubber sleeve and the screws on the back of the multimeter to replace the battery.
Replace with NEDA 1604, 6F22, or equivalent 9V battery. Disconnect the test leads before
opening the back of the multimeter.
Fuse Replacement
Fuses will rarely need replacement and are normally only blown due to operator error. To
replace the fuses, open the battery cover by removing the rubber sleeve as well as the screws
on the back of the multimeter. Disconnect the test leads before opening the back of the
multimeter.
Replace the damaged fuse with a new one with the same ratings. This meter uses two fuses:
Fuse1: 400mA, 600V, FAST, Min. Interrupt Rating 20000A, Ø10X38mm
Fuse 2: 10A, 600V, FAST, Min. Interrupt Rating 20000A, Ø10X38mm
