Zero Position Calibration
The actuator position is indicated in the Current Size dialogue on the left-hand side of the screen.
This is the current separation of the edges of the clamps or platens. For this measurement to
have meaning, a zero position must be defined. This is a position where the grip or platen tips
would just touch each other.
The Move to Size command is also dependent on a correctly defined zero position.
An actuator zero position is preset during manufacturing and quality check. However, the zero
position should be re-calibrated on initial system setup and whenever the grips, platens, load
cells, or risers are changed. Changing these components will always alter the zero position
slightly.
There is a software utility to automatically calibrate the zero position using a spring of known
length provided with the UniVert system.
The calibration spring is placed between the grips or platens. The calibration utility slowly moves
the grips or platens together until a small load is detected when contact with the spring occurs. It
then assigns this position as the size of the calibration spring being used.
To calibrate the zero position, follow these steps:
1. Open the Zero Position Calibration utility by selecting Zero Position Calibration in the
Tools menu.
