... LED's are available in red, yellow and green colors. Red LED's are also offered in high-intensity or low-power versions. The versatile design of the DMS-40PC Series assures trouble-free installation and long-term operation. Differential input voltage ranges include ±2V, ±20V and ±200V. Input impedance is a minimum 800k . Non-inverting inputs are overvoltage protected to ± ...

... Cnts/°C 1. ANALOG COMMON (Pin 10): This pin is an internal, low-noise ±0.4 ±1.5 Cnts/°C ground for the DMS-40PC internally connected to pin 3 (5V RETURN). Do not connect pin 10 to either pin 3 or your system ground as this will create a ground loop and possibly result +5.00 +5.25 Volts in erroneous readings ...

... In these high-voltage cases, pin 12 should always be tied to pin 3 (5V RETURN). One of the simplified schematic's more noteworthy features is that it shows some DMS-40PC internal voltage values and also that pin 3 is the meter's zero-volt reference point — regardless of the type of power or signal source used. This is an important point to keep in mind when using digital multimeters to perform system-level measurements ...

... GND 4.5 - 18Vdc – Figure 4. 4.5-18V Power Supply Monitor 4. Floating Signal Source Measurements: A floating input is a signal that, before it is applied to the DMS-40PC's inputs, has galvanic connection (direct current path) to the meter or the meter's power supply. The circuit shown in Figure 5 illustrates ...

... Engineering Scaling and Input Attenuation: In many applications, the input signal must be scaled, or divided down, before being applied to the DMS-40PC. In some situations, the input signal exceeds the full-scale range of the meter, and in other applications, a direct one-to-one relation does not exist between the input voltage and the desired display reading ...
