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.

Easily transfer measurement data to an Excel® file

Excel® Direct Input function allows you to input measurement values directly and automatically into an Excel® file once the instrument's auto-hold function is activated. (Wireless Adapter Z3210 is necessary)

Regular inspections of GFCIs and RCDs [Photo drawing function]

Record measurement locations and measured values together.
Identify trip locations quickly and reliably!

Identifying intermittent trip events [Event recording function]

The meter records event information (times and current values) in its internal memory.
Collect data using a tablet and check for trips!

Detect minuscule leakage currents with a newly designed sensor (IEC/EN 61557-13 compliant)

The core and shielding are constructed from high-permeability magnetic materials.
The CT sensor features a uniform coil.
The CM4002/CM4003 complies with the performance standard set forth in IEC/EN 61557-13, an international standard on leak clamp meters.

High-reliability leakage current measurement

1. Uniform measurement sensitivity inside jaws: When affixed around a wire, sensitivity is uniform regardless of the position of the conductor inside the jaws.

2. Resistance to the effects of external magnetic fields: Shielding made of high-permeability magnetic material blocks magnetic fields from the surrounding environment.

3. Elimination of the effects of highfrequency currents: A low-pass filter eliminates high-frequency capacitive leakage currents from inverters and other equipment.

Measurable conductor diameter up to φ40 mm

The jaws have a maximum diameter of φ40 mm and can be used to pinch thick cables or multiple cables at once.
