Detector Current Overload Threshold - Defines the current limit of the detector. If the de-
tector pulls more current from the high voltage, the over-current fault is activated. Setting
the detector current overload threshold to 0 disables the current overload fault.
Configurable positions are:
• Ones Place (0-9)
• Tens Place (0-9)
• Hundreds Place (0-9)
• Decimal (right most on/off )
Range: 00.0-999

Long-pressing the MODE button will toggle to live value display. Long-press
MODE button again to return threshold setting.
Response Time - The response time can be fixed, or it can operate in one of two auto modes.
When operating in fixed response mode, response time is a very predictable response. Set-
ting the Response Time to a fixed value is useful primarily when performing surveys to a
fixed MDA (Minimum Detectable Activity) level.
When operating in Auto-Response mode, the instrument will vary the Response Time based
on the Auto-Response Rate selected (Fast or Slow) and the current Count Rate. When the
instrument detects a sudden change in count rate from the detector, the response time is
reduced to 1 second to quickly show the new value.
If all characters are flashing, the mode is being selected. The mode must be changed to fixed
(all numbers flashing) before fixed time can be set. Once fixed mode is selected, pressing the
OK button will allow for normal digit selection.
Configurable positions are:
• Modes (F[ixed]-F[ast], F[ixed]-S[low], A[uto]-F, and A[uto]-S)
• Ones Place (0-9)
• Tens Place (0-6, 6 forces max Response Time of 60)
Range: Auto or Fixed Fast and Slow, or 0-60
User Defined Count Time - Defines the user configurable count time of the COUNT mode
in seconds. Setting Count Time to 0 enables continuous count until reset.
Configurable positions are:
