Table 4-1. Automatic Calibration Parameters

Auto Cal YES/NO	Set to YES
Output Tracks YES/NO	Set as desired to con-
	figure analog output
	tracking.
Cal Intvl XD XH	Set the desired time
	between calibrations in
	number of days and
	hours (1 year max).
Next Cal. XD XH	Displays the time left to
	the start of the next
	calibration. Set the de-
	sired time until the start
	of the next calibration (1
	year max). If nothing is
	entered here, the unit
	will automatically enter
	the Cal Intvl and count
	down from that.
Gas Time 0:00	Set the amount of time
	for calibration gases to
	be turned on in minutes
	and seconds; allow
	enough time for signal
	value to stabilize.
Gas Time 0:00	Set the amount of time
	for calibration gases to
	be turned on in minutes
	and seconds; allow
	enough time for signal
	value to stabilize.
Purge Time 0:00	Set the amount of time
	for the gas lines to clear
	in number of minutes
	and seconds.

2.Fully Automatic Calibration Setup. In order for the IFT system to calibrate automatically, the parameters from the CALIBRATE sub-menu (shown in Table 4-1) in the IFT have to be entered.

Once these parameters have been set, the system will initiate calibration with- out operator intervention as set by the

CAL INTVL parameter.

3.Manually Initiated Fully Automatic Cali- bration Procedure. The following pro- cedure relates to an operator initiated calibration, either by a remote switch (CAL INIT on interconnect board) or selected at the IFT by pressing the CAL key using an MPS 3000 Multi- probe Gas Sequencer.

(a)Press SETUP to display the SETUP sub-menu. Select Calibra- tion. Ensure that Auto Cal is en- abled. Set the cursor on Auto Cal. Press ENTER. Set Auto Cal to YES if not already done.

(b)Press the CAL key. Select Perform Calibration. "Press ENTER to start Automatic Calibration" will appear on the LCD display. Press ENTER to start. Refer to Table 5-5, CALI- BRATE O2 Sub-Menu.

Abort Time 0:00	Set the amount of time
	allowed between key
	functions before the
	calibration procedure is
	aborted in number of
	minutes and seconds.
Res Alarm ____	Set the desired resis-
	tance alarm between 50
	to 10,000 ohms.
