5. Load Cell Interface
PCE-N45F-IO
PCE-N45F-DA
It can be connected with 6x350Ωanalog load cells (around 58Ωminimum resistance), to confirm the
range of the load cells, the total resistance (TSR) can be calculated with the formula as below:
Before connecting the load cells, make sure the TSR is above 58Ω, if it’s less, the indicator can’t work.
Besides this, the cable distance must be considered, too, below is the maximum distance suggested:

Division
Division to be chosen：0.0001，0.0002，
0.0005，0.001，0.002，0.005，0.01，0.02，
0.05，0.1，0.2，0.5，1，2，5. Default: 0.001
Note: Only the below two conditions ok, the
chosen division can be accepted:
1：1000 =< F.S./Division = < 20000.
2：F.S./Division = multiple of 100.
Press or key to change the
division, Press Enter to save and

Press or key to change the
division, Press Enter to save and

change
Zero Calibration
Press key to return without change
Press or key to choose √or X,
If √chosen, press key to enter zero
calibration, or return directly.
When there is nothing on the scale and it’s
stable, press key to start zero
calibration.
The indicator is sampling the A/D data of
zero point, it ends when it became 0% from
100%.
Weight Calibration
Press key to return without change
Press or key to choose √or X,
If √chosen, press key to enter weight
calibration, or return directly.

Put the weight on the scale
Input the weight value the same as the
calibration weight
Press key to move the cursor.
Press key to change the digits.
Press key to save the change and
start to calibrate.
Press key to cancel and return.
The indicator is sampling the A/D data of
calibration point, it ends when it became 0%
from 100%.
The weight value is too small.
Trouble shooting：
1、 The weight is really too light.
2、Wrong connection of the signal
cable or excitation cable
Calibration done.
Full Calibration
This calibration is jointed the zero calibration and weight (capacity) calibration, prease refer
to above steps.
Calibration parameters

14
This parameter can be retrieved and can
be modified, after tested well, please record
those three parameters for use in future.
When the data in EEPROM get problem,
reload those three parameters, it doesn’t
need to do calibration again.
If the same model indicator to be changed
and those three parameters reloaded, it
doesn’t need to do calibration, either.
Input the weight value the same as the
calibration weight
Press key to move the cursor.
