Details

The easy-to-read display features an analog style bar graph to help identify measurement trends or fluctuating signals. When working in low-light environments, the auto ON/OFF backlight adjusts for the best visibility while maximizing the battery life. The dual-line display capabilities enables two measurements or one measurement along with a math function to appear on the screen simultaneously.

This unit features advanced features such as data logging record measurements to the meter's internal memory at an user-specified sampling interval. This unit provides convenient measurement monitoring and recording from a PC connected to the meter's optical isolated USB interface. Additionally, measurements stored in the meter's internal memory can be exported using the provided PC application software.

Operation Highlights

Provided Application Software

PC software is available for logging measurement data at specified intervals with data and time stamp. The user can log up to 100,000 data points in graph or table format. The measurement data recorded in the field can be exported using the software for analysis.
