NOTE: Signal Output Check stays active indefinitely until the user stops the function. There
is no automatic timeout for this feature.
To end simulation mode, hold magnet over PGM1 or PGM2 for 3 seconds. The display will either move to the
prior menu item or move to the next menu item respectively.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds.
3.5.8 Restore Factory Defaults
Restore Factory Defaults is used to clear current user configuration and calibration data from memory and
revert to factory default values. This may be required if the settings have been configured improperly and a
known reference point needs to be re-established to correct the problem.
This menu item appears as: “Restore Defaults”.
NOTE: “Restoring Factory Defaults” should only be used when absolutely necessary. All
previously existing configurational inputs will have to be re-entered if this function is executed.
A full 10-second magnet hold on PGM 2 is required to execute this function.
From the “Restore Defaults” text scroll, hold the programming magnet over PGM2 until the “” prompt
appears and continue to hold 10 seconds. The display will scroll “Restoring Defaults”, and then will revert to
the “Restore Defaults” text scroll.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll “Restore Defaults” 4 times and then return to Normal
Operation).
Following the execution of “Restore Defaults”, the IR-700 will revert to its factory default settings. The
default settings are:
 Serial ID = 01. The Serial ID must be set appropriately by the operator (Section 3.5.5).
NOTE: The following must be performed in order before the sensor can be placed in operation.
 AutoSpan Level = 50 %LEL. AutoSpan level must be set appropriately by the operator (Section 3.5.2).
 Gas Type = CH4. The Gas Type must be set appropriately by the operator (Section 3.5.3).
 Gas Factor = 1.0. The Cal Factor must be set appropriately by the operator (Section 3.5.4).
 Sensor Gain: Sensor gain settings are lost. Sensor Gain must be performed (Section 3.5.6).
 AutoZero: AutoZero Calibration Settings are lost. AutoZero must be performed (Section 3.4).
 AutoSpan: AutoSpan Calibration Settings are lost. AutoSpan must be performed (Section 3.4).
