... CMV is ±2V, and all models are overvoltage protected to ±250V (on their non-inverting inputs). All DMS-40LCD meters are fully functional and operate from a single +5V supply (draw- ing 3.5mA max single 9V supply/battery (drawing 2.5mA max.). All models feature autopolarity changeover and overrange indication. A display HOLD function is standard on all non-backlit models ...

... Figures 5 and 6. Figure 5 uses a 5V-powered meter. Figure 6 uses a 9V-powered meter. Both fi gures show a DMS-40LCD-0/1 with pin 2 tied to pin 1 yielding a ±2V input range. Connecting pin 10 (ANALOG COMMON) to (–) INPUT LO (pin 12) provides the reference point for the meter’s input. ...

... The circuit can be calibrated by fi rst measuring the actual battery volt- age with another meter and then adjusting the gain-adjust potentiom- eter on the back of the DMS-40LCD until a similar reading is obtained. If possible, the resistors in the divider should be ±1% metal-fi lm types with TCR’s less than 50ppm/°C. ...
