Safety Information

A Warning statement identifies hazardous conditions and actions

that could cause bodily harm or death.

A Caution statement identifies conditions and actions that could

damage the Meter or the equipment under test.

To avoid possible electric shock or personal injury,

follow these guidelines:

•Use the Meter only as specified in this instruction sheet

or the protection provided by the Meter might be

impaired.

•Do not use the Meter or test leads if they appear

damaged, or if the Meter is not operating properly.

•Always use proper terminals, switch position, and range

for measurements.

•Verify the Meter's operation by measuring a known

voltage. If in doubt, have the Meter serviced.

•Do not apply more than the rated voltage, as marked on

Meter, between terminals or between any terminal and

earth ground.

•Use caution with voltages above 30 V ac rms, 42 V ac

peak, or 60 V dc. These voltages pose a shock hazard.

•Disconnect circuit power and discharge all high-voltage

capacitors before testing resistance, continuity, diodes,

or capacitance.

•Do not use the Meter around explosive gas, vapor or in

damp or wet environments.

•When using test leads or probes, keep your fingers

behind the finger guards.

•Only use test leads that have the same voltage,

category, and amperage ratings as the meter and that

have been approved by a safety agency.

•Remove test leads from Meter before opening the

battery door or Meter case.

•Comply with local and national safety requirements

when working in hazardous locations.

•Use proper protective equipment, as required by local or

national authorities when working in hazardous areas.

•Avoid working alone.

•Check the test leads for continuity before use. Do

not use if the readings are high or noisy.

Battery Saver

™

(Sleep Mode)

If the Meter is ON, but inactive and not connected to voltage for

more than 20 minutes, the display goes blank to preserve battery

life. To resume operation, press any button or turn the rotary

switch. To disable the Sleep Mode, refer to the Power-Up

Options section.

Sleep Mode is always disabled in MIN/MAX record mode.

Backlight

Press Qto toggle the backlight on and off. The backlight

automatically turns off after 40 seconds. To disable backlight

auto-off, refer to the Power-Up Options section.

Display Hold

XWWarning

To avoid electric shock, when Display HOLD is

activated, be aware that the display will not change

when you apply a different voltage.

In the Display HOLD mode, the Meter freezes the digital display.

1. Press fto activate Display HOLD. (Kis displayed.)

2. To exit and return to normal operation, press for turn the

rotary switch.

WkCHEK

If a dc or ac voltage greater than about 3 V is present across the inputs

when the meter is set to kCHEK, the meter switches automatically to dc

or ac voltage mode and displays the voltage.

When kCHEK is activated, the meter has low input impedance (LoZ)

≅3 kΩ. This load can alter the voltages in electronic control circuits. Do

not use kCHEK to measure voltage in circuits that could be damaged by

a 3 kΩload.

Note

CHEK can be effectively used to eliminate “ghost”

voltages.
