ESS-03 Calibration
An ESS-03 channel can be calibrated using the auto calibration method or the
single calibration method.
NOTE: ESS-03 calibration must be done with the hose and probe attached.
If you are calibrating a chlorine sensor, be sure the hose/probe does
not have a particle filter installed.
Calibrating the ESS-03 Sensor Using Auto Calibration
The calibration instructions below assume a standard 4 plus PID plus ESS-03
instrument configuration.
There are several ways to calibrate a standard 4 plus PID plus ESS-03
instrument:
• separate cylinders for the standard 4 sensors, PID sensor, and ESS-03
sensor (3 cylinders total)
• 5-gas cylinder for the standard 4 sensors plus PID sensor and a separate
cylinder for the ESS-03 sensor (2 cylinders total)
• separate cylinder for the PID sensor and a 5-gas cylinder for standard 4
sensors plus ESS-03 sensor (2 cylinders total)
See “Calibration Supplies and Equipment” on page 69 for a description of the
necessary calibration supplies. See Table 23 on page 191 for available
cylinders. Make sure your calibration cylinder is appropriate for the ESS-03
detection range.
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 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.
