## MEASUREMENT TYPE AND CAPABILITIES 

- Measures 0-5 or 0-10 VDC process signals with 32 user-selectable span ranges (via S1, S2), displaying 3-1/2 to 4 1/2 digits of resolution. 

- Choice of two user selectible modes of operation: unipolar (supports only positive readings) and bipolar (supports negative output readings). 

- A high-input impedance helps maintain accuracy with a variety of signal sources. 

- The meter’s measurement terminals are electrically isolated from the power terminals through a DC-DC converter, providing a high common-mode input range (±48V) for the input (relative to the power terminals), simplifying a wide range of measurement applications. 

- Meter requires an external 12VDC power supply (not included).

**Brightness Adjust** – This single-turn potentiometer supports adjustment of the meter’s LED display brightness for maximum readability. Turning the pot clockwise increases brightness, while turning it counterclockwise decreases brightness. 

**Offset Adjust** – This 12-turn potentiometer supports the offset adjustments of the span ranges. See the span range selection table for the maximum allowed offset for each span range. Turning the pot clockwise will give a negative offset, while turning it counterclockwise give a positive offset. 

**Gain (Scale)  Adjust** – This 12-turn potentiometer supports gain adjustments of the span ranges. This allows the user to select values between each of the span ranges, between 1780 to 20300 (unipolar mode) and -9785 to 9785 (bipolar mode). See the span range selection table for the maximum allowed gain for each span range. Turning the pot clockwise decreases  (-) the gain, while turning it counterclockwise increases (+) the gain (see Span Ranges below). 

**S1 & S2** – 6-position dipswitches provided for configuration the meter’s various options. See Meter Configuration below for details.

This example illustrates an application where the voltage output sensor is connected to terminals 3 and 4, where terminal 3 is the negative input terminal (-IN) and terminal 4 is the positive input terminal (+IN). 

The 12V power supply (not included) connects to terminals 1 and 2, where terminal 1 is the negative power supply terminal (-VS) and terminal 2 is the positive power supply terminal (+VS) and the sensor is powered from a separate external power supply. Note: it is possible to power both the sensor and the meter from the same power supply provided the sensor can operate from +12VDC.

If the meter is set to<br>bipolar mode with the same settings, 0 V input results in a count of -<br>6000 on the display, while 10 V results in a count of +6000 on the<br>display. SW2 on S2 controls whether the meter is in unipolar or bipolar<br>mode. Unipolar mode can display values between 0 to +20000<br>depending on the span range setting.

When the span range dipswitch settings are all turned OFF, the decimal placement is automatically chosen based on the input value. For example, for 0-5 V the decimal placement is 0.000. For 0-10 V the decimal placement is 00.00. When any of the span range switches are turned ON, the decimal point placement has to be manually selected. SW3 through SW5 on S2 control the decimal point placement options as shown. Setting only one of the switches on at a time allows the user to choose the decimal place they desire. 

QTY 2 potentiometers for adjusting gain and offset are enabled by SW6 on S2. In the “OFF” position, the trim is disabled and the meter runs from factory calibrated span ranges. In the “ON” position the trim is enabled, allowing user to vary the gain and offset of the span range. The gain adjustment allows the user to adjust the span of the meter to any number between 1780 and 20300 (unipolar mode) and -9785 to +9785 (bipolar mode) with the span range setting (see span range table above). If the meter is out of calibration the operator can use the gain or offset adjustment for correction only when one of the span range settings is set, not when displaying the physical input voltage.

## Murata Power Solutionss 

## TECHNICAL NOTES 

## **1. Calibration** 

This meter is calibrated at the factory at the time of manufacture. If the meter is out of calibration the operator can use the gain or offset adjustment (Trim Enable) for correction, only when one of the span range settings is set, not when displaying the physical input voltage. However, calibration may no long be within datasheet specifications. 

## **2. Protection and Fusing** 

This meter contains an internal PTC fuse as well as other protective elements that are intended for protection against brief electrical transients and misconnect conditions. Additional external protective components such as fuses and transient suppressors may be required depending on the application in which the meter is deployed. 

## **3. Noisy Power Supplies** 

In systems with noisy power supplies, connecting an external, non-polarized capacitor across the +VS and -VS inputs can help reduce measurement errors. In certain situations, the use of twisted pair or shield wiring may be required. 

## **4. Installation** 

**IMPORTANT!** To ensure safe and reliable operation, DMS01 meters must be installed and serviced by qualified technical personnel. Contact Murata Power Solutions if there is any doubt regarding their installation or operation. 

## **5. Over-range Limit**
