  There are several reasons why the counter value on your Mitutoyo Measuring Instruments might be incorrect: * The parameters might not be correctly set for the type of Linear Gage. To resolve this, set the correct parameters. * The peak mode might be set to maximum value, minimum value, or run-out width. If so, set the peak mode to current value display. * The HOLD signal might be input. In this case, check the external input.

Why can't I connect my Linear Gage to Mitutoyo EJ-102N Measuring Instruments?
- K
  Kevin WeberAug 26, 2025
  There are a couple of reasons why a Linear Gage might not connect to your Mitutoyo Measuring Instruments: 1. You might be trying to connect a Linear Gage with a 6-pin or 8-pin connector. Use the optional adapter cable in this case. 2. You might be trying to connect a Linear Gage that does not support differential square wave output. Note that the EJ Counter can only be connected to a Linear Gage that provides differential square wave output. Other Linear Gages can be used in combination with the EC Counter or EH Counter.

What does the "-.-.-.- .-.-.- -" display with flashing periods mean on Mitutoyo EJ-102N Measuring Instruments?
- S
  sharptravisSep 4, 2025
  When the numeric display on your Mitutoyo Measuring Instruments shows "-.-.-.- .-.-.- -" with flashing periods, it means the Linear Gage is in origin detection mode, indicating the origin detection wait state. When the connected Linear Gage with origin mark is operated, the origin is acquired, and the display switches to counter display.
