Safety & Warnings
Normal use of test equipment exposes users to a certain amount of danger from electrical shock, especially when testing where exposed high voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart can stop most human heartbeats. Voltage as low as 35 volts DC or AC rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltages are even more dangerous. Normal work habits should include all accepted practices to prevent contact with exposed high voltage and to steer current away from the heart in case of accidental contact with a high voltage.
There is some danger of electrical shock from the power supply output, which produces a maximum of 60 volts DC. Several possible test conditions using this power supply can create a high voltage shock hazard:
– If the equipment under test is the “hot chassis” type, a serious shock hazard exists unless the equipment is unplugged, or an isolation transformer is used.
– If the equipment under test is “powered up” and uses high voltage in any of its circuits, the power supply outputs may be floated to the potential at the point of connection. High voltage may appear at unexpected points in defective equipment. Do not float the power supply output to more than 100 volts peak with respect to chassis or earth ground.
– If the equipment under test is “off” and uses high voltage in any of its circuits under normal operation, discharge high-voltage capacitors before making connections or tests. Some circuits retain high voltage long after the equipment is turned off.
Use only a polarized 3-wire AC outlet to ensure that the power supply chassis, case, and ground terminal are connected to a good earth ground, reducing the danger from electrical shock. Avoid exposing high voltage needlessly. Remove housings and covers only when necessary. Turn off equipment while making test connections in high-voltage circuits and discharge high-voltage capacitors after removing power.

Basic Usage & Operation Tips
Before taking measurements, ensure the multimeter is set to the correct function and range. Connect the test leads securely to the device and the circuit under test. For voltage measurements, place the leads parallel to the component; for current, connect the leads in series. Use the Data Hold button to freeze readings when needed. Always start with the highest range if unsure of the expected measurement to avoid damaging the meter.
Troubleshooting & Maintenance
If the display shows erratic readings or no response, check the battery and replace it if necessary. Inspect test leads for damage or wear and replace if faulty. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. If the multimeter fails to operate correctly after these checks, consult the full manual for detailed troubleshooting steps or contact customer support.
Safety Reminder
Always observe safety precautions when working with electrical equipment. Do not exceed the specified voltage and current limits. Avoid measuring live circuits if you are unfamiliar with proper electrical safety procedures. Use insulated test leads and wear appropriate protective gear to prevent electric shock or injury.
