Board Revisions Q and R
1. Letters indicate jumper position. Jumpers are installed on pins adjacent to letters.
2. Use 5 mm (0.2") jumpers for locations designated by a capital letter.
3. Use 2.5 mm (0.1") jumpers for locations designated by a lower case letter.
4. 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, but can also be set up via RS232/485 using special PC-compatible setup software
(available at no charge). 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.
