Diagnostic Mode includes four screens which display gun data:

•Voltage (kiloVolts) Screen

•Current (microAmperes) Screen

•Alternator Speed (Hertz) Screen

•Low Voltage Lock Screen

NOTE: You must be in Operating Mode to adjust the low voltage setting; the setting is not adjustable in Diagnostic Mode. However, the voltage adjustment switch (VA) can be set to HI or LO in Operating Mode and in Diagnostic Mode.

To enter Diagnostic Mode, press and hold the LO SET (LS) button for approximately 5 seconds. The display will go to the Voltage (kiloVolts) Screen, page 13.

To advance to the next screen, press the LO SET button again.

To exit Diagnostic Mode, press and hold the LO SET button for approximately 5 seconds. The screen will return to Operating Mode.

NOTE: If the gun is detriggered while in Diagnostic Mode, the last screen viewed will be displayed when the gun is retriggered.
