3130 Pump not working, pump limit too low?

If the pump on the 3130 calibrator seems to not be working, ensure that the pump limit is set to at least 300 psi (20 bar).

Here is the info from the manual about this,

Pump Limits
To prevent overpressure of sensitive devices the maximum pressure (pump limit) can be set. Go through the menu list until PUMP is shown. When in this mode, use SELECT and the arrow buttons to change the pump limit. Push the DONE SET softkey to save the selection and go to the main menu. This limit can be set to 10 % above full scale.

See the below menu map from Figure 7 in the manual to change the Pump Limit. The below image is in the below pdf file also.
