Teledyne ML – T101 Operation Manual Calibration Procedures

6.7. MANUAL CALIBRATION IN INDEPENDENT OR AUTO
REPORTING RANGE MODES
If the analyzer is being operated in Ind or Auto Range mode, then the High and Low
ranges must be independently checked.
When the analyzer is in either Independent or Auto Range modes the user must run a
separate calibration procedure for each range. After pressing the Cal, CALZ or Cals
buttons the user is prompted for the range that is to be calibrated as seen in the CALZ
example below:
Continue Calibration as per
Standard Procedure
SAMPLE H2S STB = XXX.X PPB H2S =XXX.X
< TST TST > CAL CALZ CALS SETUP
ZERO CAL M H2S STB XXX.XX PPB H2S =XXX.X
< TST TST > ZERO CONC EXIT
Analyzer enters
ZERO CAL Mode
See Table 5-1 for Z/S
Valve States during
this operating mode
SAMPLE RANGE TO CAL: LOW
LOW HIGH ENTR SETUP
SAMPLE RANGE TO CAL: HIGH
LOW HIGH ENTR SETUP
Wait until H2S
STB falls below
0.5 ppb. This may
take several
minutes.
Once this selection is made, the calibration procedure continues as previously described
in Sections 6.2 through 6.6. The other range may be calibrated by starting over from the
main
SAMPLE display.
6.7.1. CALIBRATION WITH REMOTE CONTACT CLOSURES
Contact closures for controlling calibration and calibration checks are located on the rear
panel CONTROL IN connector. Instructions for setup and use of these contacts can be
found in Section 5.1.2.
When the appropriate contacts are closed for at least 5 seconds, the instrument switches
into zero, low span or high span mode and the internal zero/span valves will be
automatically switched to the appropriate configuration. The remote calibration contact
closures may be activated in any order. It is recommended that contact closures remain
closed for at least 10 minutes to establish a reliable reading; the instrument will stay in the
selected mode for as long as the contacts remain closed.
