SAFETY INFORMATION

The following safety information must be observed to insure maximum

personal safety during the operation at this meter:

1. Do not use the meter if the meter or test leads look damaged, or if you suspect
that the meter is not operating properly.

2. This meter is not recommended for high voltage industrial use; for example,
not for measurements of 440 VAC or 600 VAC industrial power mains. The unit
is intended for use with low energy circuits to 600V AC/DC or high energy
circuit to 250 VAC or DC.

3. Use caution when working above 60V dc or 30V ac rms. Such voltages pose
a shock hazard.

4. When using the probes, keep your fingers behind the finger guards on the
probes.

5. Measuring voltage which exceeds the limits of the meter may cause damage
and expose the operator to a shock hazard. Always respect the voltage limits
as stated on the meter.

6. If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

OPERATION

Before taking any measurements, read the Safety Information Section.

Always examine the instrument for damage, contamination (excessive dirt,
grease, etc.) and defects. Examine the test leads for cracked or frayed insulation.
If any abnormal conditions exist do not attempt to make any measurements.

Auto Power-down mode

If unused for about 30 minutes, the tester will power-down automatically. If you
should diseble Auto Power-down mode, press SELECT buttom when you turn on
the meter.

Back-Light and Data-Hold Switch ( >2sec),( H ):

Press this button briefly to activate DATA-HOLD mode. The " H " annunciator is
displayed.
Press this button for 2 seconds to turn the Back-Light on. As this also activates
the DATA-HOLD mode, briefly press the button to return to normal display. To
turn the Back-Light off press again for 2 seconds.

W/ / )

The SELECT Function button is Yellow in color. Press it to toggle to the alternate
function (AC, Audible continuity, Diode and capacitance) shown in Yellow on the
meter face.

Voltage Measurements

1. Connect the red test lead

to the "VW" jack and the black test lead to the

"COM" jack.

2. Set the Function/Range switch to the desired voltage function.

3. Connect the test leads to the device or circuit being measured.

4. For dc, a (-) sign is displayed for negative polarity; positive polarity is implied.

Frequency Measurements

1. Set the Function/Range switch to the ACV position, and then press Hz-%
button toggle the voltage/frequency/duty cycle mode.

2. Connect the red test lead to the "VW" jack and the black test lead to the "COM"
jack.

3. Connect the test leads to the point of measurement and read the frequency
from the display.

8

Duty Cycle Measurements

1. Set the Function/Range switch to the ACV position, and then press Hz-%
button toggle the voltage/frequency/duty cycle mode.

2. Connect the red test lead to the "VW " jack and the black test lead to the "COM"
jack.
