Teledyne 7500ZA Calibration parameter range of value, External O2 sensor, Reverse Range

Settings and Calibration Model 7500ZA

4.Enter calibration gas concentration for zero and span. Use the UP or DOWN key to increment or decrement the displayed value one digit at a time. When the correct number is displayed for that digit, use the SIDE key to move to the next digit and repeat the increment/decrement process with the UP/DOWN keys.

5.After setting, save the entry by pressing the ENT key. The saved value becomes valid with the next calibration event.

Note: Enter calibration parameters settings for each range. If a zirconia O2 sensor is installed, select 21.00 for the Zero if air is used for calibration, and use the concentration listed on the cylinder for the span value.

After saving the calibration values entered, close the Calibration Parameter screen by pressing ESC. This will return the display to the previous screen.

Note: Pressing ESC during an entry (before pressing ENT) will abort the entry leaving the previous entry intact.

Calibration parameter range of value

NOx, SO2, CO2, CO, CH4, external and built in O2 sensor:

Span:	1-105% of full scale
External O2 sensor:
Zero:	0-25%
Span:	0.1%-5% (vol.)
Reverse Range:
Zero:	100% (vol.)
Span:	95.25-95.00% (vol.) O2

The settings cannot be performed beyond the range limits.

6.2.2 Manual Zero Calibration

When setting the zero calibration in manual mode, you can set all components simultaneously or one by one.
