Multimeter Calibration Resistor Board Programmable Resistor Board 1/4W 0.1%8-Segment For Jumper Cap 0.1-9 9999999 Mω Instrument

Features:

1. The resistor board uses 0.1% for  resistor

2. The resistor is plug-in, not patch. The distance between the two pins of the patch is small, moisture makes the resistance value smaller, and the stability is poor

3. Instead of using a pull-up switch, a gold-plated pin is used. The contact resistance of the pull-up switch is too large, which affects the accuracy of small resistance values. The contact resistance of the gold-plated pin is more than half smaller than that of the pull-up switch

In addition, a high-resistance resistor board is added, which is used to calibrate the multimeter or insulation withstand voltage tester, and the high resistance meter uses RI80 high-voltage resistor with 1% accuracy. This resistor is specially used for high-voltage insulation detection standard for  resistor. If you use ordinary resistors, it won’t work. Ordinary resistors are easily affected by moisture, have high voltage coefficients, and the resistance value changes too much after adding voltage. They cannot withstand high voltage. This high-resistance resistor board can withstand 5000V.

This programmable resistor board uses a large number of 0.1% for  plug-in copper feet and 25PPM low-temperature floating resistors, which can meet the needs of factories, schools, laboratories, and technicians for variable resistors. It can replace for general resistor boxes. It is convenient and practical for engineers and does not take up space. The reliability of plug-in resistors is higher than that of chip resistors. If two resistor boards are used in series and parallel, any desired resistance value can be obtained, such as 10.000000/100.0000/1.000000K/10.00000K/100.0000K, . The resistance value of the last digit is all 0. 1. Product features: 8 segments of decimal system, a wide range of resistance can be set. Using 0.1% 25PPM copper foot resistors, the resistance value is more precise and the resistance value is less affected by moisture. Small size, no space required, convenient for engineers to debug PT100 thermometer on site
