Using a DMS-30-1 meter (+/-2V range), Vin is 0-5Vdc and the display
reading must be “000” to “1500”
Meters):
When using R2 location for a dc current-shunt, please note that the
pc-board copper traces which short out R1 can only carry currents
up to 0.2A (200mA). However, dc currents up to 2A can be accommo-
dated if a 20AWG jumper wire is soldered in location R1. Be sure R2
has a sufficient power rating to safely carry the full load current. Refer
to DMS Application Note 6 for more information on dc ammeters.
SG4
1. Assume R1 = 1.0MΩ.
2. R2 = (FSI x R1) / ( |Vin| - FSI)
3. Calibrate the meter using a known voltage source. Adjust R4 to
R2 = (1.500 x 1,000,000) / (5.0 - 1.500)
R2 = 428,571Ω or 432kΩ
compensate for tolerances in R1 and R2.

1. Install R2: R2 = FSR / (I
2. Configure the DMS-EB for span adjust using the procedure previ-
3. Apply the input signal (current) to TB1 (+) HI and (–) LO.
4. Adjust R4 for desired full scale readings.
5. Enable the appropriate decimal point using SG1, SG2, or SG3.
Using a DMS-30-0 meter, a 0.100 Ampere input must read “100.0”
