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.
