Volume resistivity of surface resistivity tester
Di*al high resistance, a current measuring instrument t*e: *T-121: volume resistivity, surface resistivity uses: Instrumentation Test
One, volume resistivity surface resistivity tester overview
This instrument can measure high resistance, and measuring current. The American company Intel large scale integrated circuit and patented technology, the instrument has the advantages of *all volume, light weight, high accuracy. Dual 3.1/2 di*al display the resistance high resistance meter and current. Limit from 1× 104 Ω～ 1× 1018 Ω, is currently the most wide measurement range, the most accurate di*al ultra high resistance meter. Current measurement range of 2× 10-4 ～ 1× 10-16A. The built-in test voltage is 10/50/100/250/500/1000V adjustable. The instrument has the advantages of high precision, good stability, showing a rapid, easy reading, applied to anti-static products such as anti-static shoes, anti-static plastic rubber products, computer room anti-static floor activities such as the resistance value of the test as well as insulating materials electrical and electronic products insulation resistance measurement. The instrument can measure the resistance, and can directly measure the weak current.
Instrument is fully consistent with and better than the national standard GB1410 " solid electrical insulating materials, insulation resistance, volume resistivity and surface resistance test method " and " American Standard ASTM D257 DC resistance or conductance of insulating materials test methods " and other standards.
Two, volume resistivity surface resistivity tester main features
Resistance measuring range 0.01× 104 Ω～ 1× 1018 Ω

Good performance is stable, easy reading
All the test voltage ( 10/50/100/250/500/1000V ) test resistance results in reading, is removed from the old high resistance meter in different test voltage or different scale should be multiplied by the coefficient of the inconvenient trouble, allowing the measurement of high resistance as the multimeter is used to measure the general resistance of samples is simple.

The 8 power supply forms: AC 220V, 50HZ, power consumption is about 5W
Four, volume resistivity surface resistivity meter working principle
According to the Ohm's law, the measured resistance is equal to voltage is applied through Rx V divided by the current I. The traditional high resistance meter is the working principle of measuring voltage V fixed, by measuring the current flows through the sampling resistor I to get the value of resistance. From Ohm's law can be seen, because the current I is inversely proportional to the resistance, but not proportional to the resistance, so the display value is nonlinear, namely the resistance to infinity, the current is zero, i.e., zero is∞, in the vicinity of the scale is very dense, with a low resolution. The scale is nonlinear. Because the measurement of different resistance, the voltage V also vary, so the average high resistance meter is poor accuracy, low resolution.
At the same time measure the voltage across the resistor V and the current through the resistor I, through the interior of the large scale integrated circuit to complete the voltage divided by the current calculation, and then the results obtained after A/D conversion to di*al show resistance, even if the voltage across the resistor V and the current through the resistor I is changed at the same time, the display resistance value is not as common due to high resistance meter that measured voltage or current change of V I change, so, even if the measured voltage, resistance, power supply voltage is measured the changes in the results have little effect, the measurement accuracy is very high ( patent ), theoretically the error can be zero, while the actual error can be done a few thousandths or extremely few.
