My 93 series tester will not run up.

The tester up travel is controlled by the over-force connector at the top left of the tester. It is a two pin round connector. If you have a DFM or CFG gauge cell, make sure connection is installed properly. In case of the DFM the power must be on and you must tare before the tester will run up. If this does not help, after the load cell is identified by the DFM, disconnect the load cell from the DFM. Tare the DFM. If the tester runs up there is a problem with the load cell.
