Calibration
The EL-3000 scale may be calibrated with any precision test weight from 10% to 100% of full scale
capacity. If the scale was ordered in a avoirdupois configuration, the test weight unit must be in pounds.
If the scale was ordered in a metric configuration, then the test weight unit must be in kilograms. The
recommended test weight is about 2/3 of the full scale capacity, but in general, the larger the test
weight, the more accurate the scale will be.

ZERO

To calibrate the scale:
1.
Turn the scale off. While pressing and holding down the
ZERO/CLEAR
key, turn the scale back on.
The message "
C 0
" appears on the display briefly, followed by a value which remains on the screen.
Allow a 20 minute warm-up period for the load cell and indicator to become thermally stable.
2.
Press
ZERO/CLEAR
to zero the value, then press the
SAMPLE
key to save the zero point value.
3.
The display will momentarily prompt "
C 1
" for the span calibration, followed by "
0.00
",
“0.000”,
or
“0.0000”
depending on the scale capacity. The rightmost digit should be flashing. Place the test
weight on the platform.
4.
Use the four directional keys shown above to adjust the displayed value to the actual test weight
value. Increase the flashing digit by pressing the
MR
key. Decrease the flashing digit by pressing the
M+
key. The position of the flashing digit may be changed by pressing the
ZERO/CLEAR
key or the
MODE
key.
5.
After setting the exact value and letting the scale stabilize, press the
SAMPLE
key to save the
value.
6.
If the calibration was successful, the display will show "
ECAL
" then freeze. Exit the Calibration mode
and enter the Normal Operating Mode by turning off the scale, then turning it back on with no keys
held down.
7. If the calibration was
not
successful, one of the error messages below will appear. Take the indi-
cated action to correct the problem, then perform a new calibration.
"Err0"
- The calibration test weight or the adjusted keyed-in weight is larger than full scale. Change
the calibration test weight or check the keyed-in weight.
"Err1"
- The calibration test weight or the adjusted keyed-in weight is smaller than 10% of full scale.
Change the calibration test weight or check the keyed-in weight.
"Err2"
- Check keyed-in weight with the actual weight placed on platform.
