Troubleshooting and Service

Troubleshooting 4

Explanation: The low battery annunciator is a reminder that while running on the battery, there is a finite amount of energy available. For the battery in this instrument and the energy consumption of the instrument, when the battery voltage drops below 5.9 volts there is less than 30 minutes of operating time left.

Symptom:

“Internal Reset Error” displayed.

	ADC
	Internal Reset Error
	Press RESET/MEASURE
	and Repeat Exposure
Cause:	Start of exposure detected during reset process.
Action:	Stop the exposure. Press the RESET/MEASURE button. Wait for the “System Not RDY”
	annunciator to extinguish. Start the exposure.

Explanation: The instrument measured a current above the start threshold while resetting the electrometer. It is assumed that the exposure was started while the reset was occurring. If the exposure did start during the reset, some unknown amount of charge was lost. The lost charge would lead to an incorrect reading.

Symptom:

“Configuration Error” displayed.

ADC

Configuration Error

Service Required

Error Number : 16

Cause:	The instrument has lost the calibration or customization data.
Action:	Convert the configuration error number to a binary value using a program such as the
	Windows® Calculator and use the table below to determine the extent of the problem.
	For example, a configuration error of “18” corresponds to a binary value of “10010” (bits 5
	and 2 set), which indicates that the customization for both the ion chamber and settings
	are invalid.
