Table 3-2 lists the indicators the instrument uses to signal that a measurement quantity has not been compensated for leakage or is not available due to the specified condition.

Table 3-2. Measurement Indicators and Conditions

Indicator	Measurement	Condition
		Automatic leakage compensation is enabled, but
? (left of value)	All Non-leakage1	the exposure started before a leakage
		measurement was available.
		Automatic leakage compensation is enabled, but
-.---	Leakage	the exposure started before a leakage
		measurement was available.
		The calculated effective time is longer than the
INVALID	Effective Time	actual exposure. This condition occurs when a
		large amount of charge is injected at the
		beginning of the exposure.
NA	Leakage	The leakage measurement is not available since
		automatic leakage compensation is disabled.
		The quantity or one of its dependents has
OVER	Non-leakage1	exceeded the maximum value. Refer to Table 3-
		3 for more information.

1All non-leakage measurements (e.g., charge, current, dose, rate, effective time, etc.)

Table 3-3 specifies the conditions that cause the Model 35040 Therapy Dosimeter to display an overrange indicator (OVER) for a measurement quantity.

Table 3-3. Overrange Conditions

Condition		Overranged Measurement1
	•	charge
charge > 19.999 mC	•	average current
	•	accumulated charge
	•	effective exposure time
accumulated charge > 1.0000 C	•	accumulated charge
