UM4.6:CS6003 Original — December 1991
The M5000 operates in one of two modes: Setup/Calibration or Weight.
Select the mode with SW1-1. Set this switch to OFF (open) during
normal operation.
4.1.8.2 Overview
The calibrator performs functional tests of the weigh scale interface card.
There are no user adjustments on the weigh scale interface cards.
During the functional test, the calibrator provides power and allows the
weigh scale interface card to perform self-tests. If any test fails to
perform correctly, replace the weigh scale interface card.
4.1.8.3 Equipment Required
The following equipment is required:
Type CS6003 Calibrator
4.1.8.4 Calibration Procedure
Use the following procedure to calibrate the card:
Step 1: Verify that the calibrator ON/OFF switch to OFF.
Step 2: Insert the weigh scale interface card in the calibrator test slot
labeled MUX.
Step 3: Turn the calibrator ON. Observe the one green and two yellow
LED indicators on the front edge of the card. The following
sequence should occur:
a. Yellow LED’s Light — The card executes power-up
self-tests
b. Yellow LED’s Extinguish and Green LED Lights —
Self-tests complete satisfactorily and card is functioning
correctly
If a yellow LED blinks at about every 2.4 seconds, switch S2
is set to an undefined scale type. Reset the switch to a
defined scale type, as listed in Table 4-18 and perform the
test again.
If a yellow LED blinks at about every 1.5 seconds or no LED’s
light, the weigh scale interface card requires repair.
