In use, visual and aural prompts cue the operator to press a data button, when the reading is transmitted to a handheld computer running customised software. Recorded data may be downloaded with a USB cable to a PC running Microsoft Excel.

VHE‘s recording anode ammeters are standard products, but handle lengths and sensor head geometry of cathode ammeters are customised. Measuring heads are pluggable for quick change, and the meter unit will identify each head, eliminating the need to recalibrate the unit before every use.

Ammeters for direct reading, without the datalogger, continue to be available.
