Pt100 SIMULATOR, Model : HD2047, Brand : DeltaOhm

Description HD 2047 is a handheld instrument designed to test and calibrate instruments with Pt100 input ( 100© a 0° C) and voltage/ current outputs, such as active or passive temperature transmitter, recorders, testers and data loggers, etc. HD 2047 simulates up to 24 fixed values, following the Pt100 scale from -100° C up to + 500° C, with a 2, 3 or 4 -wire connections. The set points selection is made through a rotary switch placed on the front part of the instrument. Whatever operating mode is chosen, Pt100 output is always active. HD 2047 can measure with high accuracy voltage/ current outputs of any transmitter connected to the instrument input: -20V...+ 20V continuous voltage range and 0...22mA continuous current range. The instrument can also calibrate and test the working process of a passive transmitter and simulates the Pt100 temperature input, providing power supply to the transmitter and measuring the current inside it with no external power supply required. The instrument is provided with three different keys: ON/ OFF turns the instrument on and off. Upon power on, HD 2047 sets automatically to voltage measuring mode. MODE selects cyclically the operating mode; by pressing the key consecutively, you select in the following order: 1. voltage measurement; 2. current measurement; 3. current measurement with 4...20mA loop power supply. RANGE during the measuring process ( voltage/ current) , this mode allows the full scale selection and the best resolution for the measuring in progress: -1.999...+ 1.999, -19.99...+ 19.99 and -199.9...+ 199.9. L’ HD 2047 is internally protected against any kind of connecting error made by the operator: it is highly recommended anyway not to exceed voltage/ current limits shown in technical data. A battery sign on the display lights up to indicate that batteries are low and must be replaced.
