Enter Test Mode
Test mode provides access to calibration, system and factory parameter modes, and to some opera-
tional values. To enter test mode:
1. Remove the stainless steel pan and place the scale on its side.
2. Open the battery cover and remove the four screws in the deep wells. Remove the scale platform
and close the battery cover.
3. Remove the two rear feet and the two screws that were covered by them. Replace the two feet if
you will be calibrating the scale.
4. Remove the two screws towards the front of the scale.
5. Grasp both halves of the scale body and place the scale on its feet. Lift the upper housing up,
rotating it towards the front to place it upside down in front of the lower housing without straining the
load cell and power cables.
6. Short the two test mode jumpers. The scale should now read at or near five zeros, and the test
mode indicator should display.
7. Rotate the upper housing back onto the lower housing. Be carefull not to pinch the load cell cable
between the two housings.
Test mode displays the internal count, initial count, direct raw count, average raw count, battery check
or A /D conversion value, and display segment check in sequence. Rotate through these displays us-
ing the
key.
