6. Operating Instructions
6.1 Powering On/Off
Rotate the main dial from the 'OFF' position to any measurement function to power on the device. To power off, rotate the dial back to 'OFF'. The device also features an Auto Power Off function.
6.2 Function Selection
Use the large rotary dial to select the desired measurement function:
- LOOP: For Loop Resistance measurements.
- RCD: For Residual Current Device testing (Trip-out current, Trip-out time, Contact voltage).
- x1/2, x1, x5: Multipliers for RCD test currents.
- AUTO RAMP: For automatic RCD ramp testing.
6.3 Keypad Functions
- MEASURE: Initiates a measurement.
- READ: Recalls stored data.
- MEMO: Stores current measurement data.
- CLEAR: Clears stored data.
- SET: Enters setup mode for parameters.
- ENTER: Confirms selection.
- LIGHT: Toggles display backlight.
- DISPLAY: Cycles through display modes or parameters.
- SLOW: Activates slow test mode for RCDs.
6.4 Performing Measurements
Connect the test leads to the circuit under test according to the specific measurement type. Press the 'MEASURE' button to initiate the test. The results will be displayed on the LCD screen.
