APPLICATION
Earth resistance measuring of simple or complex electrode systems, Ground resistivity measurements (Four terminal Wenner´s principle), and Spurious voltage according to IEC 61557-5
저항측정방법
The equipment injects an electronically generated current in the soil, and measures, with high precision, both that current and  the voltage developed in the soil by means of that current flowing through grounding diffusion resistance. The display shows the Resistance value.
조작 주파수
During R measurement operators should select the following test frequencies: 270 Hz ± 1 Hz or 1470 Hz ± 1 Hz
전압계
In the voltmeter function, the equipment operates as a CA conventional voltmeter, making it possible to measure voltages generated by parasitic currents.
측정범위
Resistance: 0 - 20kΩ  (autoranging)
Resistivity: 0 - 50kΩm  (autoranging)
Voltage: 0 - 60V~
허용오차
Resistance and Resistivity measurements: ± (2% of the measured value ± 2 digits)
Voltage measurement: ± (3% of the measured value ± 2 digits)
지시분해능
0.01Ω  in the resistance measurement.
0.01Ωm in the resistivity measurement.
0.1V in the voltage measurement.
출력 전류
The short-circuit current is limited to less than 3.5mA r.m.s. (according the IEC 61557-5  - 4.5 )
IMMUNITY TO SPURIOUS VOLTAGE INTERFERENCE
During the R measurement, it allows for the presence of spurious voltage up to 7V~.
EARTH RESISTANCE OF  AUXILIARY RODS
In the R measurement it allows Raux up to 50kΩ  with error < 30%
배터리 체크
The battery charge status is verified under normal using conditions.
ADVANCED FEATURES
Automated detection of abnormal conditions that may cause excessive errors (low battery, too high noise interference, too high test spikes resistance)
SOIL RESISTIVITY COMPUTING
When performing soil resistivity measurements, the operator informs to the EM-4055 the distance between spikes and the equipment automatically computes soil resistivity using the Wenner full equation.
SERIAL DATA OUTPUT
RS-232 @ 4800 bps. Suitable for data collection in an external serial printer, computer or data-logger.
BUILT-IN PRINTER (OPTIONAL)
For a printed register document of measured values.
전원
By means of an internal rechargeable battery, 12V   2.3Ah.
배터리충전
A smart, microprocessor-controlled, circuit that adjusts the battery charge to the optimised parameters in order to ensure highest service life. It is supplied by means of an external power supply for 95-240V 50-60Hz (provided with the equipment).
안전기준
It meets the requirements of IEC 61010-1/1990, IEC 61010, 1/1992 amendment 2
E.M.C
IEC 61326-1
ELECTROSTATIC IMMUNITY
IEC 1000-4-2
ELECTRO MAGNETIC IRRADIATION IMMUNITY
IEC 61000-4-3
환경보호
IP54 with closed lid.
최고 고도
3000m
사용환경
