Example 2: Scaling without Known Loads.
If
DSBL
Disabled
Load
Submenu was selected, instrument is ready for
scaling Without Known Loads method.
To scale without known inputs, calculate inputs based on transducer specifications
and manually enter them on the via front panel push-buttons. The following example
assumes load cells with this specification:
Maximum Load:
100.0 lb
Output:
3.0 mV/V
Sensor Excitation
10 V
Maximum Sensor Output = 3.0 (mV/V) x 10 (V) = 30 mV
1. Determine the correct values for Inputs (
IN!1
and
IN!2
).
Calculate
IN!1
and
IN!2
using the following equation:
IN
= (Sensor Output) x (Converison Number) x (Multiplier)
Conversion number is a coefficient of conversion between input values
and real full display range (10000 counts). See
Table 3.2
below for
proper conversion number.
Table 3.2 Conversion Table
INPUT RANGE
CONVERSION NUMBER
0 ~ 100 mV
10000 / (100 x 1) = 100 cts/mV
0 ~ 1 V
10000 / (1000 x 1) = 10 cts/mV
0 ~ 10 V
10000 / (1000 x 10) = 1 cts/mV
0 ~ 20 mA
10000 / (20 x 1) = 500 cts/mV
Multiplier determined by the Input Resolution setting (
RESO
in the
INPT
Menu). See
Table 3.3
below for proper multiplier.
