1. Press the ON switch. The display does a lamp test; during this time the scale does
a quick check of itself. Then the weighing system starts weigh mode.
2. Intercomp recommends that you allow the electronics to operate for three minutes
after first turning power on. This allows the electronics to become stable for
maximum accuracy before you check the calibrations.
3. Make sure no weight is on the hook. Press the ZERO switch. Press the TARE and
ZERO key to clear tare. The weight shown is zero.
4. Apply weights throughout the weighing range, and verify the correct weight is
displayed at each step. (+/- 0.1% of applied load or ±1 display graduation, whichever
is greater)
5. If possible apply a weight of 105% of capacity, and verify the scale shows OE on the
display.
6. Remove weights and verify the display returns to zero.
7. If there is a failure to meet any of the conditions above, please refer to the
Calibration Procedure.
8. When all the conditions above are correct, the scale is operational.
How to enter a number
During this routine you will be asked to enter numbers at many points. The scale will
show a number (originally all zeros) with a blinking digit. At this point the commands
listed at the bottom of the keys become active. Press the UP and DOWN arrow keys to
increase the blinking digit. Press the LEFT and RIGHT arrow keys to move to other
digits. When you are finished entering the number, simultaneously press the ZERO
and lb/kg keys. You can clear the entry by pressing CLR key.
Three point span
The scale has a three point calibration feature which reduces the effects on non-
linearity in the load cells. This requires that you place three weights on the cell during
calibration. The first weight must be greater than zero, the second greater than the
first, and the final weight somewhere between the second and the capacity.
