40B indicator displaying 'Hi or Lo, Er' when connected to a 3.33mV/V strain gauge.

This is usually an indication that the input sensor signal is out of range. Note: a 'calibration'/adjustment is always required when new pressure sensors are connected to indicator.

4-wire solution

1. Press and hold the button until 'In' is displayed;
2. Press the button once, 't.P' is displayed. Using the buttons configure as required.
3. Press the button repeatedly until 'L.S' is displayed. Using the buttons configure to minimum of input scale.
4. Press the button repeatedly until 'H.S' is displayed. Using the buttons configure to maximum of input scale. For example, if a 0-700bar pressure sensor is used, Los = 0 and His = 700.
5. Press and hold the button until 'PA' is displayed. Using the buttons configure to 99.
6. Press and hold the key until 'U.C' is displayed. Using the buttons configure to 3/4
7. Press the button once. 'F1' is displayed. Ensure that the pressure sensor is drained - no pressure or weight on pressure sensor example (extruder pipe where pressure sensor is installed is empty).
8. Press the button once. 'F2' is displayed. For a 4 wire connection system, subject the pressure sensor to 80% of F.S.
   For example, if the scale is 0-700bar, 80% = 560bar. Subject 560 bar of pressure to pressure sensor.
   Alternatively, inject a millivolt signal equivalent to 80% of F.S into pins 1 and 2 of the input (after having removed the transducer from pins 1 to 4).
9. Press the button once; 'F3' is displayed. Drain pressure sensor so that it is subjected to no pressure or weight.
10. Press and hold the button to return to the main screen.
