When Z3210 is installed
Wireless supportWireless communication capability for even greater convenience than legacy model
Compatible with Wireless Adapter Z3210 (optional). It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.
Instantly create reports by a free app (GENNECT Cross)
GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports. The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos. Optional Wireless Adapter Z3210 is necessary.
Comparator function provides PASS/ FAIL decisions at a glance
Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function. (also pair with insulation resistance measurement and low-resistance measurement) The insulation testers give you pass/ fail results using a beeping sound, LCD light, and indication right on the test lead with remote control switch (option), letting you check for insulation integrity without needing to look at the instrument.
