4 Operating Instructions

Before making any measurements always examine the instrument
and accessories used with the instrument for damage,
contamination (excessive dirt, grease, ect.) and defects. Examine
the test leads for cracked or frayed insulation and make sure the
lead plugs fit snugly into the instrument jacks. If any abnormal
conditions exist do not attempt to make any measurements.

4.1 Auto power off

Automatic power-off extends the life of the battery by turning the
meter off. After approximately 45 minutes of inactivity. The meter
turns back on if a POWER swith is pressed.

4.2 Input warning beeper

The Input Warning Beeper is a feature to protect the meter and you
from unintentional misuse. If the DMM is set to measure a voltage
while the test leads are plugged into a current jack, very high
current could result when the test lead tips are placed to the
voltage test point.
This feature warns you that the test lead needs to be changed from
a current jack to the voltage jack.
All current ranges are fused with fast acting ceramic fuses as an
added protection.

4.3 Voltage measurements

WARNING:
To avoid possible electric shock, instrument damage and / or
equipment damage, do not attempt to take any voltage
measurements if the voltage is above 1000Vdc / 750Vac. 1000Vdc
and 750Vac are the maximum voltages that this instrument is
designed to measure. The "COM" terminal potential should not
exceed 500V measured to ground.
1. Insert the black and red test leads into the COM and V-Ω input
terminals respectively.
2. Select the function and the scale wished by means of the rotary
selector. With the button AC/DC select the type of measurement to
realize: AC or DC
3. Connect the test lead tips in parallel with the circuit to be
measured (e.g. across a load or power supply). Be careful not to
touch any energized conductors. Note the reading. If the indication
of overflow appears, select a top scale.
4. When all measurements are completer, disconnect the test leads
from the circuit under test. Remove test leads from the multimeter.
