Max scale should not be more than 50% FS because of noise related issues.
Press d 27) Display flashes STRD stored message momentarily and then advances to ALR1 only, if a change was made, otherwise advances to ALR1 Alarm 1 Menu.
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
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 3.1 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 3.2 below for proper multiplier.
Table 3.3 Input Resolution Multiplier
INPUT RANGE | RESOLUTION | ||
|
| LOW | HIGH |
0 | ~ 100 mV | 1.0 | 10.0 |
0 | ~ 1 V | 1.0 | 10.0 |
0 | ~ 10 V | 1.0 | 10.0 |
0 | ~ 20 mA | 1.0 | 10.0 |
