R4 REF. CAL R3 R5 R2 High-Accuracy Temperature Sensor Boards DMS-30PC/LCD-0 Meters U1 TB1 Description: The DMS-EB-HTB Application Boards accept inputs from usersupplied, AD590 solid-state temperature sensors. The boards can be used with any of DATEL's ±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. 1 R6 3.9k 12 Functional Specifications (TA = 25°C, VCC = +5V) +5V SUPPLY + R3 Measurement Range: DMS-EB-HTBC DMS-EB-HTBF U1 1.23V REF. 11 –55 to +150°C –67 to +199.9°F Sensor Type AD590 active linear device Accuracy: Typical Maximum ±0.3°C (or °F) ±1.0°C (or °F) Operating Voltage Range +5V (±10%) Input Current (Board only): Typical Maximum +0.8mA +1.0mA Sensor Lead Length 3 feet, maximum 1 (–) INPUT LO (+) INPUT HI PROBE CAL. – R1 200 10 REF.
