display the number. Only the weight that is over USER-OTHER-NLD.RNG can be
frozen. Scale will exit HOLD mode according to the setting of USER-HOLD-HLD.TIM.
If the time of scale variation is over USER-OTHER-NLD.RNG or is more than USERHOLD-STB.TIM, STB.ER will be displayed. Press TARE/PRESET, UNIT/DATA, ACC/
TOTAL or PRINT/FUNC to start averaging again, or press SETUP key to exit.
3.12.5 Auto HOLD (default setting)
When USER-HOLD-HLD.MOD is set to AUTO, the hold mode is auto hold mode.
Different subjects can be weighed one after another without pressing any buttons. After
entering this working mode, the scale will freeze and display the number if the scale is
stable. If the scale is not stable, but the variation is less than USER-HOLD-HLD.RNG,
the scale will average data in USER-HOLD-AVG.TIM, then freeze and display the
number. Only the weight that is over USER-OTHER-NLD.RNG can be frozen. If the
held weight is removed, and a new load is placed on the scale, the scale will
automatically hold the new number of the load.
The scale will exit HOLD mode according to the setting of USER-HOLD-HLD.TIM. If
the time of scale variation is over USER-OTHER-NLD.RNG or is more than USERHOLD-STB.TIM, STB.ER will be displayed. Press the TARE/PRESET key to start

Calibration
The configuration/calibration button must be pushed in order to calibrate the scale.
NOTE: More than 10% of the full scale weight is needed for calibration.
NOTE: In the following steps, pressing ZERO/ON/OFF will show "EXIT?", and
pressing ZERO/ON/OFF again or pressing TARE/PRESET will exit the calibration.

After entering this mode, the number of calibrations will be shown first. This
number will be increment one digit after every calibration and calibration data
saved. This counter can't be modified or erased. It counts from 0000 to 9999,
when 9999 is reached, the counter starts over at 0000.
4.
After the counter number was displayed, it will show "CaL.OFF" or "CAL.ON"
which depends on whether the sealed calibration switch is OFF or ON. If the
switch is OFF, the following steps can be done, but the result will not be
saved.
5.
Press the [TARE] key to go to next step.
6.
When ZERO is display, use
key to select ZERO to perform zero
point calibration (refer to step 4), LINE to perform linearity calibration (refer to
step 5), GEO to do Geographical calibration (refer to step 6) or INPUT to Input/
view calibration parameters value (refer to step 7).
ZERO Calibration
When ZERO is selected, remove all weight from the scale and press the TARE/
PRESET key to confirm.
The ZERO will flash when it is in the catching zero point state. After receiving
reasonable data, it will automatically continue to step 8.

Linearity Calibration
1.
When LINE is selected, press the TARE/PRESET key to access linearity
calibration.
0% weight will be displayed after CAL.P0 is shown.
2.
Remove all weight from the scale. Press the TARE/PRESET key to confirm
and calibrate the zero point.
The zero weight will flash. After calculating the reasonable zero-point
data, the zero weight will become steady.
When the first default standard weight is displayed after CAL.P1 is
shown, it will be calibrated on standard weight for the first point.
3.
Place the corresponding weight (more than 10%FS weight) onto the scale.
The default standard weight is 100%FS.
4.
Use the
keys to enter the value of the loaded weight. Before
entering this value, you can press and hold the UNIT/DATA key to change the

The indicator will flash the input standard weight. When this weight
number becomes steady, it means the stable and reasonable data
corresponding to the standard weight has been received. After this, the
indicator will automatically continue to the next step. If this point cannot
be calibrated correctly (E.g. the weight load on the scale is too small, the
input data is incorrect), it will display CAL.Er and return to step 2 for recalibration.

Display ADC Output Code
In this mode, you can examine the stability of weighing system and increment the ADC
output code corresponding to the loaded weight. Please note the following:
l
The increment of ADC code for full scale weight must be larger or equal to
10 times of selected display division. Otherwise, the calibration cannot be
properly completed.
m
l
PS-USB Service Manual
e.g. The display division is 0.1kg. Load 100kg standard weight on the
platform, the increment of ADC code should be at least more than
10x100kg/0.1kg= 10x1000=10000. In this case, the scale can be
calibrated. Otherwise, a smaller division needs to be chosen.
The variation of the ADC code should be small. Otherwise, the calibration
cannot be properly completed.
