using the known nominal value of the load cells. The zero value is defined by
automatic measurement, but the nominal (rated) value is defined by manual
entry.
1. Measuring the zero value of the characteristic curve when the scale is
not loaded:
Call the “AdJ” menu.
Go to the “MEAS” (measurement) sub‐menu.
Zero value:
- Leave the scale unloaded
- Call up sub‐menu “ZEro”
- The current measured value is displayed. The value is displayed in
mV/V
(2.0000 = 2 mV/V)
- Wait for a steady measurement display
- Make a note of the measured value (mw0) for later input
- Press the
“CE”
key to exit the measurement display
2. Calculating the nominal (rated) value of the scale:
As the WE2107 is factory‐adjusted in mV/V, the nominal value can now be
calculated in mV/V. The nominal value of the scale characteristic curve is
composed of the zero value and the weighing range. As the zero value has
already been measured, it only remains to define the weighing range.
Weighing range
=
Load cell sensitivity [mV/V]
V
Maximum scale capacity
Maximum load cell capacity
The load cell sensitivity is normally 2mV/V (at maximum load cell capacity) .
The maximum load cell capacity is stated on the load cell type plate. The fol
lowing applies
Maximum scale capacity < Maximum load cell capacity
So the weighing range result is a value in mV/V.
3. Entering the characteristic curve
If you now add the value for the weighing range to the previously measured
zero value, you obtain the nominal value of the scale (mw1). The character
istic curve can now be entered:
- Call the “AdJ” menu.
- Go to the “InPut” (input) sub‐menu.
