Maintenance
This section discusses calibration of the SC-01 and describes
troubleshooting procedures for the SC-01. It also describes how to change
the SC-01’s batteries as well as how to replace the sensor.
WARNING: RKI Instruments, Inc. recommends that service,
calibration, and repair of RKI instruments be performed
by personnel properly trained for this work.
NOTE: Replacing sensors and other parts with original equipment does
not affect the intrinsic safety of the instrument.
Calibration
The optimum frequency of calibration depends heavily on how the SC-01 is
used. For example, instruments used daily may need to be calibrated
weekly or monthly, while instruments that are used only a few times a year
may need to be calibrated before each use. Typical calibration frequencies
range from monthly to quarterly. For most applications, RKI Instruments,
Inc. recommends a quarterly calibration schedule (every three months).
Make sure to develop a calibration schedule tailored to your application.
Calibrate the SC-01 while in Setup Mode. To perform a complete
calibration, enter Setup Mode as described in “Using Setup Mode” on
page 22, then perform both a fresh air adjustment and a span adjustment
while in Setup Mode. See “Performing a Fresh Air Adjustment” on page 23
and “Performing a Span Adjustment” on page 24 for instructions.
Troubleshooting
The troubleshooting table describes error messages, symptoms, probable
causes, and recommended actions for problems you may encounter with
the SC-01.
