Safety & Warnings
Normal use of the Model 1422 Test Instrument exposes users to electrical shock hazards due to the presence of high voltage during testing. A current of 10 milliamps passing through the heart can be lethal, and voltages as low as 35 volts can produce such a current under certain conditions. To reduce risk, users should:
1. Avoid unnecessary exposure to high voltage by removing housings and covers only when necessary, turning off equipment while making test connections, and discharging high-voltage capacitors after removing power.
2. Familiarize themselves with the equipment and its high voltage points, keeping in mind that high voltage may appear unexpectedly in defective equipment.
3. Use insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface for equipment, ensuring these surfaces are not damp or wet.
4. Employ the “one hand in the pocket” technique when handling an instrument probe to avoid providing a ground return path through the body.

Basic Usage and Operation Tips
Before taking any measurements, ensure the device is properly calibrated and the test leads are securely connected. Select the appropriate measurement mode using the rotary switch. For voltage measurements, connect the probes in parallel with the circuit, and for current measurements, connect them in series. Use the data hold button to freeze the displayed reading for easier recording. Always start with the highest range if unsure of the expected measurement value to prevent damage to the device.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or fails to power on, check the battery status and replace if necessary. Inspect test leads for any visible 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 device shows a constant overload indication, verify that the measurement range is correctly set and that the probes are connected properly.
Safety Reminder
Always follow standard electrical safety practices when using the Bk-precision-1422. Do not exceed the specified input limits to avoid electric shock or damage. Use caution when working with high voltages and ensure the device is rated for the application. Disconnect power before connecting or disconnecting test leads, and never operate the multimeter with damaged insulation or exposed metal parts.
