CALIBRATION
The TCW scales calibrate using metric weights and the TCWa scales can calibrate
using either metric or pound weights, depending on the weighing unit in use before
calibration.
To start calibration turn the scale off and then turn it back on. Press the TARE and %
keys together during the initial counting from 9 to 0 on the display.
The display will show "unLoAd". Remove all weight from the pan and then press the
ZERO/ENTER key to set the initial zero point when the scale is stable.
The display will then show the last calibration weight used. This value can be used
again or a new value can be entered.
To use this value press the
ZERO/ENTER key, the display will show
"LoAd", put the calibration weight on
the platform and then press the
ZERO/ENTER key when the stable
indicator is on.
Or if a different value is desired enter
the value using the arrow key to
select the flashing digit and the to
increment the flashing digit. When the
value is correct press the ZERO/ENTER
key to accept a weight. The display will
show "LoAd", Put the calibration weight
on the platform and then press the
ZERO/ENTER key when the stable
indicator is on.
Remove the calibration weight as the scale counts back from 9 to 0.
If an error message (Err 8) is shown during calibration recheck the calibration and
repeat it if necessary. If the error cannot be corrected contact
Inscale for advice.
After calibration the scale should be checked to verify the calibration and linearity is
correct. If necessary repeat calibration, especially be certain the scale is stable before
accepting any weight.
TCWa scales will also have the Lb or Kg (or g) indicator on to show the
denomination of the weight requested. If the scale was in pounds before starting
calibration the weights requested will be pound values, or if the scale was weighing in
kilograms then metric weights will be requested.
