How to use

Before use, visually inspect the device and probes for damage and ensure the battery is installed. Select the appropriate AC or DC voltage range, or set the meter to an auto-ranging mode if available. Connect the black probe to the common terminal and the red probe to the voltage input, then place the probes across the circuit points where voltage is to be measured. Read the value on the digital display and interpret it according to the expected range for the circuit under test. After measurement, remove the probes and switch the meter off to preserve battery life.

Usage recommendations

For safe operation, always observe basic electrical safety: de-energize circuits where possible, use appropriate personal protective equipment, and avoid contact with live conductors. Verify probe insulation before use and ensure the selected measurement range exceeds the expected voltage. Store the meter in a dry environment and replace batteries when low to maintain accurate readings.
