The PDS-99 has a resistance range from 1 Ohms to 1.2 Mohms while the PDS-85 and PDS-96 have a range of 0.1 Ohms to 300 Kohms and 100 mOhms to 10 Mohms, respectively. The temperature coefficient for each unit is less than 1 ppm/°C and all are capable of 2, 3 and 4 wire connection.
The accuracy of resistance for the PDS-99 (with 4 wires) at 16-400 Ohms is 0.003% (+/- 3 mOhms); from 400 Ohms to 2 Kohms the accuracy is 0.005%, and from 2-10 Kohms, 0.015%. The PDS-85 has an accuracy of 0.05% (+/- 15 mOhms) between 10-200 Ohms, 0.02% between 200 Ohms – 10 Kohms, 0.05% at 10 Kohms -50Kohms, 0.1% at 50 – 100 Kohms, and 0.5% between 100 – 300 Kohms. The PDS-96 has an accuracy of 0.05% (+/- 15 mOhms) at 0.1 – 200 Ohms, 0.02% at 200 Ohms to 2 Mohms, and 0.05% between 2 and 10 Mohms.
Both the PDS-99 and PDS-85/96 operate within a temperature range of 5-40°C and a voltage of 100-240VAC/50-60 Hz. The units feature a simple keypad operation for value selection and a back-lit LCD display for easy viewing. Additionally, each model is conveniently programmable via a RS232 computer interface. Weighing less than 9 pounds and enclosed in a robust metal housing make the resistance decades both portable and rugged.
