5.3 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.
Note:
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
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, smaller division needs to be chosen.
l
The variation of the ADC code should be small. Otherwise, the calibration
cannot be properly completed.
1.
From the weigh mode press the
[SETUP]
key until
CONFIG
is shown.
2.
Use the
[PRINT]
or
[N/G]
key to go to MISC - Code.
3.
Press the
[TARE]
key to enter this mode and display the ADC output raw
code.
4.
Press the
[TARE]
key to set the current code as a reference zero and then
display net code
5.
Press
[TARE]
again to clear this reference and display gross code. From the
net code mode, press the
[N/G]
key to select net or gross code to display, not
clear the reference code.
6.
In this mode, press the
[UNIT]
key to select displaying code that has been
filtered by no-filter, filter1 or filter1 and filter2 and corresponding annunciator
LO, OK, HI will be illuminated.
7.
Press the
[SETUP]
key to return to last menu item.
8.
Press the
[ON/OFF]
key to exit this mode
5.4 Display and Calibrate Power Voltage
In this mode, you can examine the voltage of battery or the voltage from the AC adaptor
when no battery is used. You can also calibrate the displayed voltage and set the
voltage value of low battery point.
Note:
l
The end customer normally has no need to set the value of low battery and
full-charged voltage, calibrate the displayed voltage, these have been done
in factory.
l
The normal displaying voltage is 5.6V-7.6V
1.
From the weigh mode press the
[SETUP]
key until
CONFIG
is shown.
2.
Use the
[PRINT]
or
[N/G]
key to go to MISC - Vol.
3.
Press the
[TARE]
key to enter this mode and display the battery voltage.
