This document is the operating instructions for RESISTRON PD-3 / PD-5. PD-3/5 is a precision potentiometer, which is used for external connection of temperature controllers.
This document provides operating instructions for the Ropex PD-3 (0...300°C range) and PD-5 (-0...500°C range) precision potentiometers. These devices consist of a setting potentiometer (P-3 or P-5) and a KD fine control knob with a digital display, designed to be optimally tuned for RESISTRON/CIRUS temperature controllers.
| Resistance (PD-3/PD-5) | 2kohms |
|---|---|
| Turns (PD-3/PD-5) | 3 turns / 5 turns |
| Power rating | 2.0W |
| Set point indication range (PD-3) | 0...300 |
| Accuracy Linearity | +/-0.15% |
| Insulation voltage | 1000VAC, 1 min. |
First, insert the KD knob into the front panel cutout and screw it tight. Then, screw the lock washer onto the P-3/-5 potentiometer.
The display on the knob will deviate from the value set with the potentiometer.
