DMS-30DR Series
Sunlight Readable, 3? Digit Panel Meters
APPLICATIONS
Example: For a meter with a 2V full scale input (1.999 full
scale reading) and a desired display reading of
"1000" (with an input of 20mA), V Fsr = 1.000 Volts
R Shunt = 1.000V/(0.020 – 0.004)A
R Shunt = 1.000V/0.016A = 62.5 Ohms
To calibrate the circuit of Figure 7, perform the following:
1. With 4mA applied, adjust the 50k Ω potentiometer (R2) to
display a reading of "000" (assuming that is the desired
reading).
2. With 20mA applied, adjust the gain-adjust potentiometer on
the back of the meter to display a reading of "1000". For
different full scale readings, alter the value of R Shunt accordingly.

6. Digital Ammeter: Digital ammeters are ?nding ever-increasing usage
because analog-style ammeters (moving-vane types) now cost roughly
the same as their digital counterparts. Additionally, analog ammeters
are not nearly as rugged as modern digital panel voltmeters. Figure 9
illustrates a typical ammeter application. The circuit uses a ±200mV
input meter — the preferred range for most ammeters — to measure
the voltage developed across a 0.1 Ω current shunt. The circuit shown
