Entering Pressure Calibration Data
To enter calibration data for the pressure transducer on the TF 
Probe or MISP Probe, you must list the zero and span range in 
mV (TF Probe) or FP (M2SP Probe) as well as the zero and span 
range in PSIg or kPa. 
1. To enter the Pressure window, press the [
X] arrow key to 
reach the Pressure tab and press 
[ENTER]. The screen appears 
similar to Figure 3-4 below.

Option
2. Press the [
T] key to enter the first zero value (here shown as 
mV) in the calibration table.
3. Press 
[ENTER] to open the text box. Use the numeric keys to 
enter the desired value, and press 
[ENTER] to confirm the 
entry. 
4. Press the [
X] key to move to the Pressure text box (here 
shown as kPa), and press 
[ENTER]. Again, use the numeric 
keys to enter the desired value, and press 
[ENTER] to confirm 
the entry.
5. Use the arrow keys to move to the Span boxes, and repeat 
steps 3 and 4 to enter the Span values.
6. When you have completed entering values, press 
[F3] (Exit). 
The PM880 returns to the Pressure tab at the top of the screen.
