New Gauge Calibration – Micro
NOTE: Gauges are precise measuring devices and they have been factory calibrated and matched to a
specific canister. Moving a gauge to any other canister will negate the calibration and result in inaccurate
dispensing. Should a new gauge be required, the following process must be completed to calibrate it.
1. Confirm that the plunger handle is tight on the plunger shaft.
2. Insert new gauge into canister.
3. Set gauge to first locking hole (position zero).
4. Make sure the micro knob is set to zero.
5. Apply thread locking compound to the setscrew and insert into micro knob. Tighten set screw so
that the set screw makes contact. DO NOT over tighten.
6. Check the gauge locking operation to ensure the gauge locks in on the zero setting. Over tightening
will prevent the locking pin from engaging properly.
7. Rotate the micro-knob and return it to zero.
8. Confirm that no movement can be perceived by trying to raise the plunger handle.
9. Place cap on micro-knob.
Gauge Recalibration – Micro
If gauges have been moved from one canister to another the gauges will have to be recalibrated.
To recalibrate the gauges, follow the procedure above, except instead of adjusting the set screw in the
center of the gauge, adjust the setscrew in the plunger handle.
