The process of performing a Microman / Microman E / Pos-D calibration adjustment should always be the last option. Verifying that all other components are in good working condition and part replacement, as needed, should be done first. Pipette damage and lost parts may occur if attention to detail is not maintained. Please proceed at your own risk.
Required Microman Calibration Adjustment Tool:
Locking Cap Lever Tool – GI F148172
NOTE: For illustration purposes, these instructions focus on the Gilson Microman. The instructions below and the locking cap lever tool can also be used with the Gilson Micronman E and Rainin Pos-D.

Microman Calibration Instructions
Step 1:
Insert the open end of the Locking Cap Lever Tool into the Microman locking cap. Figure 1.0.
Once inserted into the locking cap, pry the locking cap upward.
Step 2:
Notice the locking cap is now lifted upward and out of the pipette body.
CAUTION: With the locking cap now lifted upward, any movement of the adjustment knob will affect the calibration.
Step 3:
Rotate the adjustment knob:
A. Counter-clockwise to increase the volume aspirated and dispensed ( + )
B. Clock-wide to decrease the volume aspirated and dispensed ( – ), Figure 3.0
NOTE: Only turn the adjustment knob 1/8th of a turn at a time. Large turns will grossly affect desired results. For best results, it’s recommended to make adjustments at the 10% volume.
Step 4:
Insert the open end of the Locking Cap Lever Tool into the Microman locking cap. Push it back down into the body opening until it clicks back into place. Ensure it is fully in place. Figure 4.0.
Step 5:
Check the calibration adjustment made on a 4-5 place analytical balance. Repeat steps 1-5 if additional calibration adjustment is needed.
