3. Ni - MH rechargeable batteries
4. 1000V overload protection on V, ohms, frequency.
5. 25% Manual Step plus Auto Step and Auto Ramp on mA output.

Combined the DMM you trust with the loop calibrator you need. The Process Meter puts a complete troubleshooting solution in the palm of your hand. Get in touch with more information, faster and easier with the newest member. The meter gives you the measurement capabilities you expect from our rugged, reliable DMMs plus the ability to source, simulate, or measure DC current with 1 microamp resolution and accuracy of 0.05%. Put it all together and you have the ideal tool for troubleshooting and calibrating current loop applications. So if you're tired of always tracking down a calibrator, lugging around two tools and switching back and forth, get the single best solution for doubling your power.
