1.3 Maintenance
Your DVM830L is the result of superior design and craftsmanship. The following
suggestions will help you keep your multi-meter in perfect working order:
• Keep the multi-meter dry. Wipe it immediately if it gets wet.
• Use and store the multi-meter under normal temperatures. Extreme
temperatures may shorten the life of the device or damage the battery.
• Handle the multi-meter with care. Dropping it may damage the circuit boards
or the case and may lead to malfunction.
• Replace an old or weak battery with a fresh one of the required size and type.
• Remove the battery during long periods of inactivity. This will protect the
multi-meter from possible leakage.
• Disconnect the test probes before opening the multi-meter.
• Replace a blown fuse with a new one of the same size and type.
Fuse : F 0.5A/250V (resettable
• Refrain from using this device if anomalies are detected. Do not try to repair
the device yourself: consult authorised personnel.
• Do not use the multi-meter unless the back cover is in place and fully
fastened.
• Use a damp cloth moistened with a mild detergent for cleaning purposes. Do
not use solvents or abrasive cleansing agents or solvents.

2.2 FUNCTION AND RANGE SWITCH
Select the desired function and range. It is also used to activate the device.
Place the switch in the "OFF" position when the device is not in use in order
to extend the life of your battery.
2.3 "10A" JACK
Plug in the connector for the red (+) test lead for all your 10A-
measurements.
2.4 "VΩmA" JACK
Plug in the connector for the red (+) test lead for all voltage, resistance and
current measurements (with the exception of 10A-measurements).
2.5 "Common" JACK
Plug in the connector for the black (-) test lead.
3. Operating instructions
WARNING
1) Do not measure voltages that exceed the earthing level by more than 500V in
order to avoid the risk of electroshocks or damage to the instrument.
2) Verify whether the insulation of all test leads, probes and connectors is intact
prior to activating the device.

3.1 DC Voltage Measurements

1) Connect the red test lead to the "VΩmA" jack and the black lead to the "COM"
jack.
2) Place the RANGE switch in the appropriate VDC position. Set the switch to the
highest range and work your way down if the voltage range is unknown
beforehand.
3) Connect the test leads to the device or circuit to be measured.
4) Activate the device or circuit to be measured. Both the voltage value and the
polarity will be displayed.
