No need for an auxiliary grounding rod with this earth tester, which features True RMS, a slim jaw, and can easily clamp ground wires. Kit comes fully equipped with a wireless adaptor to allow for Bluetooth wireless communication.
Compact and low-profile, this clamp-on earth tester provides AC measurement functionalities and can also measure currents ranging from leakage current on the order of several mA to load currents of up to 60 A.
Measure multi-grounded systems
Clamp on the earth cable. The instrument has two cores for voltage injection and current measurement.
Clamp at the narrowest point!
The dramatically slim 0.79" (20 mm) jaws let you finish your job easily and efficiently.
Transfer data via Bluetooth wireless communication
When the wireless adaptor is installed, Bluetooth wireless communication is enabled.
Easily transfer measurement data to an Excel file
When the wireless adaptor is installed, the 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.
Alarm function
Set the alarm to audibly and visually notify yourself that the resistance or current value exceeds the threshold.
High accuracy and repeatability
Well-designed magnetic shields eliminate the leakage flux between the two cores that often affect measurement accuracy.
LCD with beautiful back light
With the bright back light, you can easily read the measurement value even in dark locations.
Large storage capacity (up to 2000 data)
You can store up to 2000 measurement values in the field and recall them in your office later.
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.
When the wireless adaptor is installed, 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.

Earth Tester | |
Measurement Principle | Instrument has two cores for voltage injection and current measurement. From the defined voltage and measured current, the total circuit loop resistance is calculated Note: For multi-grounded systems only. In a multi-grounded system, the larger the number of grounding poles, the more accurate the measured value |
Earthing Resistance Range | 0.20 Ω (0.01 Ω resolution) to 1600 Ω (20 Ω resolution), 10 ranges Zero suppression: Less than 0.02 Ω Accuracy: ±1.5% rdg. ±0.02 |
AC Range | 20.00 mA (0.01 mA resolution) to 60.0 A (0.1 A resolution), 5 ranges Zero suppression: Less than 0.05 mA Accuracy: ±2% rdg. ±0.05 mA (30 to 400 Hz, True RMS), Crest factor 5 or less (for the 60 A range, 1.7 or less) |
Maximum Input Current (Current Measurement) | 100 A AC continuous, AC 200 A for 2 minutes or shorter (at 50 Hz/60 Hz, requires derating at frequency) |
Maximum Rated Terminal-to-Ground Voltage | 600 VAC measurement category IV (anticipated transient over-voltage 8000 V) |
Memory Function | 2000 data |
Power Supply | 2 x LR6 alkaline battery |
Continuous Operating Time | Approximately 40 hours (25 Ω measurement, backlight off, without Z3210 installed) Approximately 35 hours (25 Ω measurement, backlight off, with Z3210 installed and using wireless communications) |
Maximum Measurable Conductor Diameter | φ 1.26" (32 mm) |
Dimensions | 2.87 x 8.58 x 1.69" (73 x 218 x 43 mm) |
Weight | 21.9 oz (620 g) |
Wireless Adaptor | |
Bluetooth Communication Distance | About 10 m (line-of-sight distance) |
Operating/Storage Temperature and Humidity | -22 to 158°F (-30 to 70°C), 90% RH or less (no condensation) |
Operating Environment | Indoors, pollution degree 2, operable at an altitude specified in specifications of each measuring instrument to which the adaptor is attached |
Standards | Safety: EN61010 RF: EN300 328 RF EMC: EN301 489-1, EN301 489-17 Exposure: EN62479 |
Dimensions | 0.65 x 0.26 x 0.61" (16.4 x 6.7 x 15.6 mm) |
Weight | 0.05 oz (1.5 g) |
