RP-Series
General Features
The Texmate Model RP-4500D2 is an ultra stable, super accurate
4 1/2 digit panel meter featuring a 100KHz crystal clock. As a result of this feature, the meter provides an exceptionally high normal mode and common mode rejection. The meter measures bipolar true differential and single-ended DC voltages over four factory calibrated ranges from 1.9999V to 1200.0V full scale.
Resolution is 100V over 19999 counts, and errors due to zero drift are virtually eliminated by means of autozeroing. The meter has a multiplexed BCD output capability and as an option a parallel BCD output can be provided. Other user programmable modes of operation include an ohmmeter, current meter, ratiometric voltmeter, and special scaling with offset capability.
The differential input capability of the RP-4500D2 has a wide common mode voltage range of 3VDC and a high common mode DC voltage rejection ratio of 80dB. Common mode signals are those which are present equally on both input terminals but do not develop a differential voltage between them. This capability is particularly useful for making accurate measurements of very small signals in the presence of much larger common mode signals. Because of its noise immunity, the RP-4500D2 is ideal for measuring various balanced transducers and bridge inputs.
The 120dB normal mode rejection of the RP-4500D2 at multiples of 50/60Hz means that almost any AC mains noise present on the input signal will be rejected.
In addition to standard run/hold and display blanking options, the RP-4500D2 features specially prepared internal mounting holes and solder pads to enable user designed input signal conditioning and control. These auxiliary pads provide access to all the key operating and control circuitry of the meter including regulated 5VDC and outputs.
