NOTE: Bacharach offers a convenient Exchange
Program (where available) that allows the customer
to regularly receive pre-calibrated replacement
sensors that include a code that can be entered into
the analyzer for a quick convenient setup. Contact
Bacharach customer service for more details about
this program.
5.5. T-Stack Calibration
This procedure first zeroes and then spans stack temperature to known
temperature values.
The use of an electronic thermocouple simulator is the preferred method of
producing the desired calibration temperatures. Alternatively, ice and boiling
water baths can be used.
5.5.1. Materials Required

Thermocouple simulator (K-type)
Range: 0 to 600° F (-18 to 316° F)
Accuracy: ± 0.5° F (± 0.3° C)

(Alternatively) ice water, boiling water, thermometer
5.5.2. T-Stack Calibration Procedure
Step
T-STACK Calibration Procedure
1
Plug the simulator into the T-STACK connector located at the bottom of the
analyzer.
Alternatively: Plug the probe's thermocouple into the T-STACK connector
located at the bottom of the analyzer.
IMPORTANT: DO NOT attach the probe's gas hose to the
analyzer's GAS port; otherwise water will be drawn into the
analyzer!
2
If not already done, turn ON the analyzer and display the CALIBRATION Menu.
Note that this requires password validation (see page 35).
3
Use the UP () and DOWN () arrow buttons to highlight T-Stack, and then
press ENTER to display the CALIBRATE TS-ZERO screen.
