The option on the right of the first row can be set to TRACK or

HOLD by using the UP or Down keys. By selecting the TRACK option, the
analog outputs are enabled and with the display will track the concentration
changes while the instrument is undergoing scheduled or remote calibration
(either zero or span). By selecting the HOLD option, the analog outputs and
display are disabled and will not track the concentration changes while the
instrument is undergoing scheduled or remote calibration (either zero or span).
In the HOLD option, the analog outputs and display will freeze on the last
reading before entering calibration.

The analog outputs are both 0 to 1 volt outputs and both 4 to 20 mA

outputs.

3.3.10 Calibration/Hold Timer Setup

This Calibration Timer lets the operator adjust the time thee instrument

purges the calibration gas prior to actually start the calibration computations.
The Sample timer lets the operator adjust the time the instrument purges sample
gas after finishing a calibration before it lets the analog outputs and display track
the change in concentration.

This function and the TRACK/HOLD feature will prevent false alarms

while performing remote or autoscheduled calibrations. These functions are not
applicable if the calibration is initiated through the front panel. To enter the
Calibration/Hold Timer function, you must:

Press the System key to start the System function:
