To adjust the pressure on the Time Electronics 7194A Pneumatic Pressure Calibration Pump, follow these steps:
1. Make sure the isolating valve is open to allow pressure to be applied to the device under test (DUT).
2. Turn the pressure/vacuum selector to the "pressure" position by pulling it out.
3. Use the pressure lever to pump the pressure up. If the lever is hard to pump, check that the isolating valve is open and the airline is not blocked.
4. For fine pressure adjustment, use the fine adjust handles. Turn them clockwise to increase the pressure in increments of 0.1 mbar (10 Pa).
5. If the output pressure is unstable when using the fine adjust, check that the isolating valve is closed.
Please refer to the Time Electronics 7194A Pneumatic Pressure Calibration Pump User Manual for more detailed instructions and illustrations.
