Description: The DMS-EB-HTB Application Boards accept inputs from user-supplied,
AD590 solid-state temperature sensors. The boards can be used with any of Murata Power
Solutions’ ±200mV, 5V-powered DMS-30PC/LCD-0 Series, 3½ Digit, LED/LCD Display,
Digital Panel Voltmeters — although better performance can be achieved with either LCD
or low-power LED models. This meter/board combination provides extremely accurate
(±0.3°C) temperature measurements over the range of –55 to +150°C(with DMS-EB-
HTBC) or –67 to +199.9°F (DMS-EB-HTBF). Individual reference-adjust and probe-adjust
potentiometers allow for "fine tuning" the AD590 output to precisely match the selected
meter. A 6-wire, screw-type terminal block provides for quick, reliable, signal and power
connections.
Calibration: R4 (Reference Adjust) is factory-calibrated to +459.8mV for °F and
+273.2mV for °C (do not readjust). This measurement is taken between TB1 (pin 6) and pin
12 of the DMS-30PC/LCD-0. R1 (Probe Adjust) requires customer adjustment since every
sensor has a slightly different zero offset. Calibration is simple: connect the sensor leads to
TB1 and adjust R1 until the DMS-30's display matches a selected reference temperature
indicator.
