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 cover and the
battery/fuse door are in place and fastened securely

AC/DC CLAMP METER
AC/DC CLAMP METER
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.
Do not allow a gap between the two halves of the jaw.
Refer to the diagram at right for
the correct way to enclose a single conductor.
3) Read the ACA value on the LCD.

5
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.
Do not allow a gap between the two halves of the jaw.
5) Read the DCA value on the LCD.
Non-Contact AC Voltage Measurements
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 often
twisted. For best results, rub the probe tip along a
length of the cord to assure placing the tip in close
proximity to the live conductor.
NOTE: The detector is designed with high sensitivity.
Static electricity or other sources of energy may
randomly trip the sensor. This is normal operation
WARNING: Risk of Electrocution. Before use, always test the
Voltage Detector on a known live circuit to verify proper operation

6
Frequency Measurements
1) Set the Function switch to the Hz position.
2) Fully enclose the conductor to be measured. Do not
allow a gap between the two halves of the jaw.
3) Read the Frequency value on the LCD.
Flashlight
Press and hold the top button to turn the flashlight on.
Release the button to turn the flashlight off.
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.
Backlight display
Press and hold the “Hold Backlight” key for more than 2
seconds to turn on the backlight. This will also activate the
Data Hold function. To release the Data Hold function and
return the meter to normal operation, press the Data Hold
key momentarily. To turn off the backlight, press and hold the
“Hold Backlight” key for more than 2 seconds
AUTO POWER OFF

7
The auto off feature will turn the meter off after 7 minutes.
Battery Replacement
1) When the low battery symbol appears on the LCD
the batteries must be replaced.
2) Power down and remove the rear battery
compartment Phillips screw.
3) Lift off the battery compartment cover and replace
the two 1.5V AAA cells.
4) Replace compartment cover and secure the screw.
