12. LOAD CELL INPUT JUMPERS
Notes
1.
See Section 17 to select 10V excitation.
2.
Jumpers are 2.5 mm (0.1 in).
3.
Store spare jumpers on an unused jumper post.
SCALE & OFFSET SETUP
For load cell scale meters, scaling is normally set up from the front panel using the and
keys, but can also be set up via RS232/485 using special PC-compatible Instrument Setup
software (available at no charge). The meter allows three scaling methods to be selected:
1) Scale & Offset method, 2) Coordinates of 2 Points method, or 3) Reading Coordinates of
2 Points method. Only menu items applicable to the selected method will be presented. Please
see the Glossary for an explanation of each method.
Load cell scale meters utilize the load cell signal conditioner board, which offers sensitivity to
±20 mV full scale and 4- or 6-wire load cell connection. This board needs to be configured via
jumpers for the desired voltage range. All signal ranges are factory calibrated with calibration
factors stored in EEPROM. The meter software recognizes the board and will bring up the
appropriate menu items for it; however, it does not recognize the jumper settings. Please see
further manual sections for relay output, analog output, communications, and transducer
excitation output.
