The AT682 High Resistance Meter is an MCU controlled measuring instrument for direct readout of resistance and current. The voltage applied to the device under test (DUT) is programmable from 1 to 1000 volts. A pass/fail indicator provides a visual display of test results based on a preset limit. An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or micro ohmmeter) make low resistance measurements. Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms ( ω ). The Vitrek 4700 Precision High Voltage Meter is the top choice when you require high voltage test equipment, the 4700 offers the highest level of measurement accuracy, yet is surprisingly easy to use. Vitrek has harnessed DSP technology to provide outstanding AC & DC voltage accuracy, stability and resolution.

All this performance is built into an instrument that operates as simply as a digital multimeter. Hiresta Meter. Surface & Volume High Resistivity for Nonconductive Materials. The Hiresta Meter is an intelligent, highly precise high resistivity meter that quickly and accurately carries out measurements for various shapes and samples in the measurement range of 10 +4 to 10 +13 Ohms. This means that when doing resistance measurements, small resistances are extremely stable, while large resistances are disproportionately unstable. However, if the meter is switched to conductance measurement, a high resistance will read a low number on conductance, and a 10% fluctuation may not even be visible as a one-count fluctuation. Oct 06, 2016 · High resistance, wire insulation measurements in the range of greater than 1014Ω are made using basic, simple, readily-available items and a 6517B Electrometer/High Resistance Meter. Hioki’s resistance meters and battery testers for measuring internal resistance or impedance deliver high speed, accuracy and repeatability. Learn more. If such resistance values need to be measured, nothing but a high-voltage ohmmeter will suffice. Simple High-Voltage Ohmmeter. The most direct method of high-voltage resistance measurement involves simply substituting a higher voltage battery in the same basic design of ohmmeter investigated earlier: The Model HR2 meter measures resistance in nine ranges from 1 ohm to 1.9999 Tera ohms (1.9999×10 12ohms), and conductance in a single range of 0.00 to 199.99 pS (pico siemens, or pico mhos), all at low voltage of < 2 volts across the sample. Description: . For resistance higher than 1.9999 Tera ohms, the conductance range can be used to measure conductance down to 0.01 pS (100 T ohms).The meter has a conductance range because samples with simultaneously high resistance and high capacitance settle High Resistance Meter is designed for measuring very high resistance and related parameters of insulation materials, electronic components, and electro-mechanical components. Development and evaluation of chemoresistive polymer sensors for low concentration detection of volatile organic compounds related to food safety applications Alibaba.com offers 48,347 high resistance meter products. About 1% of these are flow meters, 1% are ph meters, and 1% are water meters. A wide variety of high resistance meter options are available to you, such as pe, plastic, and metal. Jul 25, 2017 · You are now measuring the resistance of the air between your two test leads and the resistance of that air is very high. In fact, it is so high that it is more resistance than you meter is capable of measuring. It is literally off the scale. Your meter is experiencing so much electrical resistance that is literally OVERLOADED (OL)! If such resistance values need to be measured, nothing but a high-voltage ohmmeter will suffice. Simple High-Voltage Ohmmeter. The most direct method of high-voltage resistance measurement involves simply substituting a higher voltage battery in the same basic design of ohmmeter investigated earlier: High-resistance measurements are integral to a variety of test applications, including surface insulation resistance (SIR) testing of printed circuit boards, resistivity measurements of insulating materials and semiconductors, and voltage coefficient testing of high-ohmic-value resistors.

Vitrek has harnessed DSP technology to provide outstanding AC & DC voltage accuracy, stability and resolution. To measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity,... This means that when doing resistance measurements, small resistances are extremely stable, while large resistances are disproportionately unstable.
