DaTi Net Tester

Safety Rules and Precautions

Thank you for purchasing our Digital Ground Net Tester. Before your first use of the instrument, please ensure to: Carefully read and strictly adhere to the safety rules and precautions listed in this manual to avoid potential electric shock or personal injury.

²This gauge is based onIEC61010Design, production, and inspection of safety specifications.

Exercise caution and prioritize safety when using this gauge under all circumstances.

Do not use high-frequency signal generators such as mobile phones near the instrument during measurement to avoid errors.

Please note the label text and symbols on the instrument housing.

Ensure that the instrument and accessories are in good condition before use. The insulation of the instrument and test lines must be intact, without any damage, exposed parts, or broken wires.

Before measurement, ensure that the connection plugs of the cables are securely inserted into the instrument interface.

Do not shake the test wire or suddenly disconnect or short-circuit it during measurement to avoid affecting the normal reading.

During the measurement process, it is strictly prohibited to touch exposed conductors or the circuit being measured.

Due to the potential voltage on input/output terminals and test posts, etc., sparking may occur when plugging or unplugging test cables or power outlets!

Do not measure in flammable areas; sparks may cause an explosion.

If the housing or test lines of the instrument break during use, causing exposed metal, please discontinue use.

Do not place or store instruments in high humidity, condensation-prone areas, or under direct sunlight for extended periods.

Please avoid frequently turning on and off this computer; the power on/off process should be done with care.5~10Instant buffering time.

Please provide the Chinese content to be translated.220V/50HzWhen using power supply, if extending power with an extension cord, ensure the cord's current capacity exceeds15AAvailable for use.

Please note the measurement range and operating environment specified by this instrument. The use, disassembly, calibration, and maintenance of this instrument must be performed by authorized personnel only.

In the event that using this instrument poses a danger due to its condition, it should be immediately discontinued and sealed, with handling to be conducted by authorized institutions.

"Safety warning symbols in the instruments and manual must be strictly adhered to, as the user must follow the safety procedures outlined in this manual."

High voltage at gauge output, please ensure the test line is securely connected. Only press the test button after your hand is away from the test line to avoid electric shock.

Summary

The Digital Large Ground Resistance Tester, also known as the Power Frequency Ground Resistance Tester or Ground Resistance Meter, is a commonly used instrument for measuring ground resistance. It features a new type of variable frequency AC power supply, dual-frequency measurement technology, a large, touchable color screen, and microprocessor technology, meeting the impedance requirements for two-wire, three-wire, and four-wire tests. It can also measure soil resistivity, step voltage, distributed potential, contact voltage, current phase, and other parameters. Suitable for telecommunications, power, meteorology, data centers, oil fields, power distribution lines, transmission towers, gas stations, factory grounding grids, lightning rods, etc., and meets the standards for power substation and lightning protection device testing instruments. The instrument is characterized by its precise, fast, simple, and stable and reliable performance.

This test instrument outputs a high open-circuit voltage of400VLarge short-circuit current capability5AMicroprocessor control and automatic dual-frequency technology can accurately measure and calculate under strong interference conditions.50HzThe ground impedance value under AC frequency is clearly displayed on the large screen. Meanwhile, it is also stored.100Group data, resistance measurement range:0.030Ω～2000Data can be printed out via a thermal printer.

The Digital Large Grounding Resistance Tester consists of a main unit, test cables, grounding rods, etc., and features functions such as reading, reviewing, saving, and printing historical data.
