    Tips: Troubleshooting C512 Handheld Precision Signal Source Calibrator
    1. The calibrator cannot turn on or automatically shut down.
    Possible reasons:
    a. Low battery
    b. Poor contact between the plug of power adapter and the socket of the generator
    Troubleshooting:
    a. Replace the 4 AA batteries (1.5V) with new ones.
    b. Ensure the plug is tightly fitted to the socket.

    2. The device displays “ERROR”.
    Possible reasons: Low battery
    Troubleshooting: Replace the 4 AA batteries (1.5V) with new ones.

    3. The signal output is intermittent.
    Possible reasons: Poor contact of the probe
    Troubleshooting: Ensure the probe wire and probe clip is connected well; the probe wire and the output of signal generator are tightly fitted.
