Safety

To ensure safe operation and service of this meter, follow these instructions:

• Before use take note that the metal objects and the conductors of

this meter can be very dangerous

• When testing the meter, pay extra attention to safety to prevent

shock and arc blast injury where hazardous live conductors are

exposed

• Before each use, inspect the meter; look for cracks or missing por-

tions of the housing or output cable insulation as well as loose or

weakened components, pay particular attention to the insulation

surrounding the jaws

• Operating limits of Unit are as indicated on the back of the Meter

(600V in Category III)

• Use extreme caution when working around bare conductors or bus-

bars, contact with the conductor could result in electric shock

• Before turning the instrument on, press the trigger several times to

ensure the jaw is closing correctly

• When the meter is on and auto-calibrating, do not open the jaw or

hook it around any conductor

Maintenance

• Keep the surfaces of the jaw clean, any dirt can cause malfunctions

• Use a soft damp cloth to clean the jaw faces, do not use abrasives,

solvents or alcohol

• Avoid any shocks to the meter, especially to the jaw faces

• After each measurement, press the HOLD button to save battery

power

• Remove the batteries from the meter if not to be used for a pro-

longed period of time

Operating Instructions

ON/OFF

The button switches the meter on and off. Press the button once

to turn the meter on and then hold the button for two seconds to turn

the meter off. Once the meter is on, it begins to auto-calibrate. While it’s

calibrating, the display will go from CAL 9 to CAL 0. Wait until the meter

has nished before pressing anything or opening the jaws. Once the

calibration is completed, the meter will return to the measurement mode

that was last used. If it was in resistance mode, the LCD will display the

primary resistance measured value.

Ground Resistance Measurement

1. After turning the meter on, you can press the button to

congure for resistance measurement mode.

2. Hook the jaw around the leads or electrodes to be tested.

3. If the and symbols appear on the display, this indicates that

the jaw is not closed properly. Press the trigger several times to close

the jaw properly. Once the symbol disappears, the meter returns

to the usual measurement mode.

4. Read the measurement value on the display.

5. If the NOISE symbol appears on the display, indicates that the current

in the grounding loop has been disturbed. The resistance

measurement can be affected.
