The PRTD-X-6-0.001 part of a broad line of high programmable decade boxes. It provide direct resistance substitution as well as RTD (Resistance Temperature Detector) simulation, in a wide selection of ranges, tolerances and ratings.

The PRTD-X-6-0.001 Programmable RTD Simulator is a precision resistance source with excellent characteristics of stability, temperature coefficient, and power coefficient.  These features combined with a low virtually constant zero resistance make for very versatile instruments.

The PRTD-X-6-0.001 Programmable RTD Simulator features two optional special settings. An "open circuit" and a "short circuit". These modes are useful for obtaining reproducible transitions between settings, i.e. break-before-make or to short between settings. The "short circuit": setting also provides a reduced zero resistance.

Operation is both local using convenient direct-reading front panel thumbwheel switches, and remote with optional parallel RS-232, or IEEE-488 interfaces.
Both can provide an optional extra "10" position for each decade.

The PRTD-X-6-0.001 has fixed minimum resistance setting (4 Ω or specified by customer) are suitable for Programmable RTD (Resistance Temperature Detector) simulations. This design virtually eliminates the effect of zero resistance and relay contact resistance, providing the specified absolute accuracy over its entire range.

The programmable decade box employees, high-quality gold-plated tellurium-copper five-way binding posts serve to minimize the thermal emf effects, which would produce errors in dc resistance measurements. All other conductors within the instrument, as well as the solder employed contain no metals or junctions that could contribute to thermal emf problems.

DRIVERS - TEST KEYBOARD

To aid the user in operating the PRS/PCS/PLS, Two “Keyboard” Controller programs - the easiest way to control GPIB or RS232 devices without writing a program - are available from IET. This Keyboard programs automatically finds your device at start-up and it lets you enter just the data that you want to send to the device. This program works with ICS, Measurement Computing and National Instruments controllers. 

For GPIB   IEEE-488.1 and IEEE-488.2 interface
Download ICS_GPIBkybd_Install.zip

Unzip the file and follow instructions to install. Open the application.  You may use the Find Listeners button to confirm that the PRS unit is recognized. Other instruments may also be recognized at this time.

Enter and set the Address to the PRS address. Use the window to send a command string to the PRS, where the command string is constructed as described in the operating manual. A command string might be, for example:
SOURce:DATA resistance string
