IR4056-20Insulation resistance meter - Japan's home hioki

IR4056-20 andIR4057-20Features insulation resistance meter

1. Strengthen the comparator function for instantaneous judgment PASS / FAIL
   Comparator compares the measured value and the preset reference value to determine PASS / FAIL. Since when has this feature , IR4056-20 and IR4057-20 can contact analyte in the test line, providing instant PASS / FAIL judgment.
   
   In addition , the comparator function allows users to determine the PASS / FAIL by light and tone. You will be prompted beeps when "PASS" and green LED lights , and "FAIL" is displayed long red continuous tone measurement screen backlight . When using the optional remote control test line L9788-11, can also be determined "FAIL" through the red LED lights easily test line.
   
   Technicians will often require 100 positions were measured in the same building , so the instrument can be continuously PASS / FAIL judgment will greatly improve work efficiency.
2. Measurements easy to read
   Most of the built- in test equipment comprises in the case of longer wire, and therefore , the influence of interference from other nearby sources of interference and the wire , the insulation resistance meter reading is often unstable. Because IR4056-20 and IR4057-20 measurement readings can be fixed using a variety of shows , so even in unstable environments can easily read the measurement value.
3. Improve the safety of the high voltage output
   IR4056-20 and IR4057-20 in the measurement of high -voltage equipment , with a high voltage of 500V and 1000V output. Generally , when the high voltage into a low voltage device can be easily damaged if neglect . Therefore, in order to prevent the occurrence of such cases, to prevent misuse of this new product with high voltage output.
   
   Output 500V or 1000V requires two steps ; function keys will be placed in a certain position, then press the flashing button to cancel the high- voltage output lock function. Thus, the resistance of the table through the misuse of the function keys to prevent careless high voltage output.
4. Demand for AC / DC voltage measurement to meet the growing field of solar energy and electric vehicles
   As the solar energy and increasing demand for electric vehicles , an increasing need to have the DC voltage measuring instrument . To this end , HIOKI developed IR4056-20 and IR4057-20 both AC and DC voltage measurement .
5. Suitable for measurement and inspection of electric vehicles , hybrid electric vehicles and building electrical equipment
   In addition to the measurement of low resistance DC 200mA , IR4056-20 and IR4057-20 can be safe conductors and electric / hybrid cars in line with JIS C 60364 standards set forth in the building electrical equipment safety contact resistance measurements of non- direct measurements .

Additional features IR4057-20 insulation resistance meter

IR4057-20 measurement results can be displayed in the form of a histogram , making it easier to judge. In addition , IR4057-20 high performance comparator function faster than IR4056-20 judgment (IR4057-20 about 0.3s, IR4056-20 about 0.8s).
