Appendix F: ESS-03 Toxic Sensors • 187
NOTE:
RKI Instruments, Inc. recommends that you dedicate a regulator for use with
chlorine (Cl
2
) gas and that you do not use that dedicated regulator for any other
gases, particularly hydrogen sulfide (H
2
S).
1 . To calibrate the standard 4 sensors and/or the high range PID sensor, follow the
instructions outlined in “Calibrating Using the Auto Calibration Method” on
page 71.
NOTE:
Be sure to calibrate the ESS-03 sensor with the hose and probe attached.
2 . When you review the auto calibration values, confirm that the ESS-03’s auto
calibration gas value matches the calibration cylinder.
a. If you need to change an HCN channel’s auto calibration value, the procedure is
slightly different since PH
3
can be used to calibrate the HCN channel. When you
move the cursor to HCN in the Concentration Screen and then press and release
the POWER/ENTER button, the Alternative Gas Screen will appear. The HCN
concentration will be flashing.
b. Use the
▲
AIR and SHIFT
▼
(PANIC) buttons to change the HCN concentration.
As the HCN concentration changes, the PH
3
concentration will also change. If
you are using HCN to calibrate the HCN sensor, adjust the HCN concentration
until it matches the concentration listed on your cylinder. If you are using PH
3
to
calibrate the HCN sensor, adjust the HCN concentration until the PH
3
concentration matches the concentration listed on your cylinder.
