3.5 inch TFT color screen 4, 5, or 6 digits adjustable display
Rugged design for harsh environments. Passed a 1-meter drop test Three years warranty for the 220, and one year for the battery pack
Misuse protection and Electrical isolation
Up to 30V voltage on any two sockets and up to 1A current on current sockets will not damage the calibrator. The calibrator will return to normal condition as soon as the voltage or current is removed. Measuring, sourcing and loop power circuits are electrically isolated each other.
Rechargeable Li-ion battery for 15 hours uninterrupted use. Battery life will be reduced when 24V is applied. The rechargeable battery is replaceable.
