11. DC VOLTS, AMPS, PROCESS, STRAIN INPUT
The DC Volts, Amps, Process and Strain meters utilize the DC signal conditioner board, which
needs to be configured via jumpers for the desired voltage or current 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 setup of the following:
relay output (16), analog output (17), communications (18), and transducer excitation output
(19).
1. Use 5 mm (0.2") jumpers for locations designated by a capital letter.
2.
Use 2.5 mm (0.1") jumpers for locations designated by a lower case letter.
3. Store spare jumpers on an unused jumper post not associated a capital letter.
SCALE & OFFSET SETUP
For DC voltmeters & ammeters , a scale factor of 1 and an offset of 0 are used for direct
readings in (milli)volts or (milli)amperes. Decimal point selection does not affect the displayed
digits. For example, 0-20V or 0-20 mA signals can both be displayed as 0-20000. A full scale
of 20000 may be displayed as 20.000 mA or 20000 µA. Use with a current shunt will require a
scale factor to be set. For example, for a 500-100 (500A, 100 mV) shunt, divide 5000 (the
desired full scale display with 0.1A resolution) by 10000 (displayed value with 100 mV when
the scale factor is 1.0) for a scale factor of 0.5.
For process & strain meters, scaling is normally set up from the front panel using the and
keys. The meter allows three scaling methods to be selected: 1) Scale and offset,
2) Coordinates of 2 points, and 3) Reading coordinates of 2 points. Only menu items
applicable to the selected method will be presented.
