1 Initial Charge & Initial Auto-zero Calibration
To achieve the best performance
from your Si-CA 8500 portable
combustion gas & emissions
analyzer, please practice the
following instructions and
maintenance recommendations.
A new Si-CA 8500 should be charged with the unit powered off for 12 to 24 hours.
It is not suggested to charge the unit for more than 24 hours when powered off.
Use the 100-240 Volt AC charger having a 12 Volt DC/2.5A output supplied with the
instrument to carry out the instrument charge.
Upon powering ON the Si-CA 8500, press OK to initiate the 180 second auto-zero
calibration cycle. This should be done with the sampling probe and hoses disconnected from
the analyzer, and in a dry, fresh air environment preferably outdoors. After the autozero
cycle is complete, the probe can be connected and testing can begin.
Attach the probe and sampling line. One hose connects to the SAMPLE IN connector,
and the other hose connects to the positive (+) pressure connector (1 m/40” &
1.5m/60” probes do not have a second hose).
The thermocouple connector from the stack gas sampling probe should be connected
to the TEMPERATURE 1 thermocouple connector on the analyzer. The probe can then
be inserted into the stack, and sampling can begin. Use the MEASURE key to view the
stack gas measured and calculated parameters.
The Si-CA 8500 has an automatic condensation drain pump that pumps the condensate
out the bottom of the analyzer every 25 minutes (default setting). For extremely high
moisture applications, it is recommended to change the pump setting to drain the
condensate more frequently (every ~10 minutes). This can be easily changed through the
analyzer’s SETUP keypad menu. In PUMP, display pump status:
a. AUTO - Automatic sample and dilution control mode is selected, and typical ow-rate
b. SAMPLE - Pump remains in sample mode (dilution disabled), and the current duty
cycle of the pump is shown.
c. DILUTE - Pump remains in dilution mode, and the current duty cycle of the pump is
d. PURGE - Purge mode is enabled, and the sample pump is turned off.
e. OFF - All pumps are turned off.
Complete portable tool for emissions level monitoring of boilers, engines, and other
combustion equipment, the Si-CA 8500 emissions monitoring device can boast as many
as 9 gas sensors. Detecting one of the widest spectra of gases (O
CxHy, High CO, VOCs and H
S), the Si-CA 8500 is designed to measure, record and remotely
transmit combustion parameters.
