Frequently Asked Questions
What does “no Enc” mean?
If the readhead is off the scale, or the readhead cable is unplugged from the digital
display, an “no Enc” will appear on the display. To clear error:
1. Be sure the readhead is on the scale.
2. Unplug the connector from the display for one second.
3. Reconnect the readhead cable to the digital display.
The battery clips seem to be very loose. Is this normal?
Yes. DO NOT attempt to bend these clips or wedge anything between them and
the case. These clips are designed to expand when the two case halves are
screwed together.
Can I mount the scale/readhead without the connector link/guide clip?
The connector link and guide clip serve to provide an accurate method of
transferring the movement of the moving part to the readhead or scale, while also
absorbing any stresses that may occur. If they are not used, the warranty could be
voided.
The display reads numbers but they seem to be random.
Be sure the readhead is oriented correctly on the scale. One end of the scale is
black. Be sure that the arrow on the readhead is pointed in the correct direction.
The display does not change as the scale/readhead moves.
The display is in the HOLD mode. Press & release the Hold button.
Product Communication
ProScale's electrical interface allows the readhead position to be read directly or through
the digital display by a computer or other data acquisition device. Interface diagrams are
available upon request .
