DIAGNOSTICS - for the CHECK OUT PROCEDURE

If display fails to come on at all: check for power at outlet.

Check the 1/2 amp panel front fuse.

Possible model numbers are:

GBM, 140, 14R, 220, 240, 24R, 420, 440, 44R, 940, 184. If model number is not correct for you unit:

see the next page, SELECTING CORRECT MODEL.

If display shows randomly drifting numbers: check to see load cells are plugged in.

If display shows about (- 1250.0) or ( -4500):

check that the weigh bin is in place properly.

If display is steady but not near zero:

An over stressed load cell will display a permanently high or low reading. Recalibrate load cells; next section.

If there is no response from the display when the bin is touched: check for damaged wires to load cells.

check that load cell plug screws are secure.

If response is not sensitive or does not return to its start point: check for interference around weigh bin.

If pressing * does not display (PASSWORD):

you are not in the normal power-up mode or the keypad doesn't work. Normal mode is indicated by the ABSENCE of the letter M or P at the left of the display.
