Safety & Warnings
Normal use of the instrument exposes users to electrical shock hazards, especially when measurements are taken in equipment with high voltage. Electrical shocks causing 10 milliamps of current through the heart can be lethal. Voltages as low as 35 volts dc or ac rms are dangerous and can produce lethal currents under certain conditions. Higher voltages pose an even greater threat. To reduce risk, users should:
1. Avoid making measurements at circuit points exceeding the maximum input voltages listed in the specifications to prevent instrument damage. Even at low voltage points, avoid touching high voltage points. AC line voltage may be present in power input circuits even if the equipment is off.
2. Familiarize themselves with the equipment being tested and its high voltage points, but remember that high voltage can appear unexpectedly in defective equipment.
3. Use the “one hand in the pocket” technique when handling an instrument probe to avoid contact with grounded metal objects.
4. Use insulated floor material or a large insulated floor mat and an insulated work surface, ensuring they are not damp or wet.
5. Connect the counter’s ac power cord only to a 3-wire outlet to ensure the instrument’s chassis, connectors, and probe ground lead are at earth ground.

Basic Usage and Operation Tips
Before starting 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, use the parallel connection method, while current measurements require series connection. Always start with the highest range if unsure of the expected measurement to prevent damage. Use the Data Hold button to capture and review readings easily.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or fails to power on, check the battery and replace it if necessary. Clean the test leads and connectors regularly to maintain good contact. Avoid exposing the device to extreme temperatures or moisture. If the device shows “OL” on the display, it indicates an overload; switch to a higher range or check the circuit connections. For persistent issues, refer to the service manual for detailed diagnostics.
