DPM 950 is the standard model of the DPM 950 series. It has an accuracy of 0.05% and a temperature stability of 100ppm/°C. It can be connected to an IDC interface. The full-scale voltage and current can be adjusted. It has automatic zeroing and polarity functions. It has an LED backlight and a single-rail version alarm. It is suitable for portable equipment.
This two‑page guide details the physical dimensions of the DPM 950 multimeter, offers a connector sourcing guide, and explains the IDC mounting method. It also describes how scaling resistors Ra and Rb can be used to adjust the full‑scale reading and the need for periodic recalibration.
The document lists the pin assignments for power, measurement inputs, reference voltages and annunciators, and includes safety notes, operating temperature range, and basic electrical specifications such as accuracy, supply current and input leakage. It is intended for designers integrating the DPM 950 into equipment or for service personnel needing quick reference data.
| Accuracy (overall error) | 0.05 % min, 0.1 % typ |
|---|---|
| Linearity | –1 count |
| Sample rate | 3 samples/sec |
| Operating temperature range | 0 °C to 50 °C |
| Supply voltage | 5 V nominal |
| Supply current (without backlight) | 150 mA |
| Backlight current | 50 mA |
| Input leakage current (Vin = 0 V) | 1 – 10 pA |
Two scaling resistors, Ra and Rb, may be fitted to alter the full‑scale reading; the meter must then be re‑calibrated.
Pin 3 provides the negative power supply (V‑) and pin 4 provides the positive power supply (V+).
The device is rated for operation from 0 °C to 50 °C.
The DPM 950 uses a 3‰ digit LCD module.
