What is it?

New product PR200 series programmable resistance box: 0.1mΩ steps programmable resistance box with REAL passive resistance output over 0.03Ω-100MΩ range, 10ppm typ. TC and 0.015%+3mΩ init accuracy.

Features

• 4-W output (compatible to 2-W)
• Setting via kaypad (just like QR10's)
• 0.96" OLED display (larger than QR10's)
• Rechargeable battery (high-temperature type, can work @up to 70℃)
• USB-B port (for serial communication) and battery auto-charging
• DB9 port (for RS-232 , RS-485 and power supply)
• Switching speed auto-adjust based on auto-detection of the different power supply sources (battery/USB/DB9)

Spec. of model PR200A-0-1M:

What makes it special?

Unlike QR100/101 that the accuracy is based on "reading" or "process value" (for example when you need a 100.0 Ohm while the device can only output 99.95 Ohm - although it will tell you it's 99.95 Ohm), PR200 makes it possible to output the exactly the resistance value "100.0000" you want.
