The Sanwa RD700 is a 4000 count digital multimeter with 0.3% accuracy.
The RD700 is designed for low voltage circuits, home appliance measurements, and small communications equipment. This device comes in two variants, the , and the RD700. The only difference between the two is that the RD700 does not include the AC True RMS feature for measuring AC sine waves.
The RD700 comes with a 4000-count large format display and has an accuracy of 0.3%. It can be used to measure basic electrical parameters such as voltage, current, resistance, frequency, capacitance as well as temperature (300 ℃ max) using an optional K-type thermocouple sensor (K-250PC). The device features an ADP function for the current sensor, so that users can use the compatible current clamp sensor (CL-22AD & CL-22DC) to measure current in a conductor.
This device has an auto-power off mode that turns the device off after 30 minutes (cancellable). It also features an alarm for wrong probe insertion in the current terminal. The meter has a fuse of 20 kA and has a protective holster with a wall hanger/lead holder and a tilting stand.
Includes meter, rubber holster, instruction manual and one set of test leads.
