4. Safety Information

!
Caution! Refer to the explanation in this Manual
Double Insulation
This meter has been designed to be safe in use, but the operator must use caution in its operation. The rules
listed below should be carefully followed for safe operation.
1. NEVER apply voltage or current to the meter that exceeds the specified maximum:
2. USE EXTREME CAUTION when working with voltages greater than 25VAC rms. These voltages are
considerd a shock hazard.
3. NEVER operate the meter unless the back co ver and t he battery/fuse door are in place and fastened
securely

5. Operation
AC Current Measurements
1) Set the Function switch to the ACA range.
2) Press the jaw trigger and clamp around, fully enclosing a single conductor.
3) Do not allow a gap between the two halves of the jaw.
4) Refer to the diagram at right for the correct way to enclose a single conductor.
5) Read the ACA value on the LCD.
DC Current Measurements
1) Set the Function switch to the DCA range.
2) Press the ZERO key to null the meter display.
3) Press the Trigger to open the current sense Jaw.
4) Fully enclose the conductor to be measured.
5) Do not allow a gap between the two halves of the jaw.
6) Read the DCA value on the LCD.
Non-Contact AC Voltage Measurements
WARNING: Risk of Electrocution. Before use, always test the Voltage
Detector on a known live circuit to verify proper operation
1) Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet.
2) If AC voltage is present, the detector light will illuminate.
NOTE: The conductors in electrical cord sets are of ten twisted. For b est results, rub th e probe tip alo ng a
length of the cord to assure placing the tip in close proximity to the live conductor.
NOTE: The detector is d esigned with high sen sitivity. Static electricity or other so urces of energy may
randomly trip the sensor. This is normal operation
6. Flashlight
Press and hold the top button to turn the flashlight on. Release the button to turn the flashlight off.

7. Data Hold

To freeze the current reading on the LCD, press the "Hold Backlight" key. The word HOLD will appear on the
LCD while the meter is in the Data Hold mode. To release the Data Hold function and return the meter to normal
operation, press the "Hold Backlight" key again. The word HOLD will switch off.
