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 often twisted. For best results, rub the

probe tip along a length of the cord to assure placing the tip in close prox i mity 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

Flashlight

Press and hold the top button to turn the flashlight on. Release the button to turn the flashlight

off.

Data Hold & Backlight button

To freeze the current reading on the LCD, press 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. The backlight function illuminates the display and is used

when the ambient light to too low to permit viewing of the displayed readings. Press the

Hold & Backlight

button for 2 second to turn the backlight on and press the button a

second time to turn the backlight off.

(only ACA 200A Range)

Peak Hold

The Peak Hold function captures the peak AC/DC current 10~282.8A. The meter

can capture peaks as fast as <1 0 millisecond in duration.

MAX/MIN (DCA,DCV,ACV, Resistance range)

1. Press the MAX/MIN key to activate the MAX/MIN recording mode. The display

icon "MAX" will appear. The meter will display and hold the maximum reading

and will update only when a new "max" occurs.

2. Press the MAX/MIN key and "MIN" will appear The display icon "MIN" will

appear. The meter will display and hold the minimum reading and will update

only when a new "min" occurs

3. Press the MAX/MIN key and a "MAX MIN" will appear. The meter will display

the present reading, but will continue to update and store the max and min

readings.

4. To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds.

DCA ZERO

The DC Zero feature removes offset values and improves accuracy for DC current

measurements.

To perform a zero, select ADC and with no conductor in the jaw:

1. Press the DC ZERO button 2 Sec. to zero the display. "ZERO" will appear in the display.

The offset value is now stored and removed from all measurements.

To view the stored value, press the DC ZERO button. "ZERO" will flash and the stored

value will be displayed.

To exit this mode, press and Hold the ZERO button until "ZERO" is no longer in the

display.

True RMS (ACA or ACV)

The term stands for "Root-Mean-Square," which represents the method of calculation

of the voltage or current value. Average responding multimeters are calibrated to read

correctly only on sine waves and they will read inaccurately on non-sine wave or

distorted signals. True rms meters read accurately on either type of signal.

Battery Replacement

1. Remove the one rear Phillips head screw

2. Open the battery compartment

3. Replace the

Requires two "AAA" batteries (UM4 R03)

4. Re-assemble the meter
