Milliohm Meter/ English
EN-4 2016-9-10 / V001
Electrical Specification:
(23°C±5°C, 80% RH or lower)
Accuracy: ±(0.3% reading + 4 digit)
Measurement by the Four Wire type one pair of
coated clip:
To guarantee a higher precise measurement of this digital Ohmmeter, an accurate
wide range impedance testing equipment, and to eliminate any improper influence of
measurement, especially in effect of the impedance of testing leads, the following
procedures should be followed.
FIG (2)
1. Please refer to the table shown above, a testing current is passed in individual
testing range (from HI end to the LO end).
2. The specific electric current flows through any unknown resistance RX.
3. The Voltage VX can be measured on RX1, RX2 terminals, VX = RX x IS
therefore RX = VX / IS
4. The unknown resistance value can be given on LCD display from VX voltage
value to be measured.
5. To obtain accurate impedance measured without any resistance value
impedance between terminals RX1 and RX2.
