Probe provides wide dynamic measuring range
The first of a new range of high frequency current probes, the HFR3000 provides a wide dynamic measuring range up to 3000A AC at frequencies from 1Hz to 1MHz
This technique makes testing safer and quicker by not requiring disconnection before testing. The Heme Geo 30 indicates and measures true RMS current flow from a few microamps up to 30A. In continuity mode, resistance from 0 to 1510ohm can be measured, and an audible alert sounds above 40ohm.
The high/low function automatically evaluates the measured value by comparing against upper and lower limits, sounding the buzzer when the limits are exceeded.
The hold function freezes the display during measurement; this is particularly useful where the instrument is used in difficult-to-access locations.
The memory function stores individual measurements, or measurements may be recorded automatically.
The timing between measurements may be programmed from 1 to 255s.
Once stored, the captured value may be retrieved to the instrument's display.
This simplifies field measurement and later documentation.
The compact and rugged design makes the Heme Geo 30 an easy-to-use lightweight instrument for confined spaces and harsh environments.
Safety features conforming with IEC1010 and a special jaw design provide confidence when working in hazardous voltage areas, and conformance to EMC standards ensures high reliability through reduced susceptibility to electromagnetic influences.
