The Simplifies performing leakage, breakdown, and resistance testing, as well as volume (Ω-cm) and surface resistivity (Ω/square) measurements on high resistivity materials. The restive sample (unknown resistance) is connected at two points; the “Non-Sensitive Terminal” is the source of current (or of 1 volt in the pS range), and the “Shielded Sensitive Terminal” is connected to a high-impedance amplifier, which uses feedback to hold the sensitive terminal at ground potential.

A deviation limit (50 mohm in this example) is set up around both sides of a setpoint. The display is available with red or green LEDs. Innovative open jaw technology. This is partly because the change in deflection itself is small when the resistance measured is too small in proportion to the intrinsic resistance of the ohmmeter (which can be dealt with through current division), but mostly because the meter's reading is the sum of the resistance of the measuring leads, the contact resistances and the resistance being measured. -rush current measurement captures ‘power-on’ surge current with accuracy and repeatability High voltage measurement of 1000 V AC + DC true-RMS, 600 V AC, and 1000 V DC allows the user to perform multiple tests with only one tool (355 only) Resistance to 400K ohms coupled, Description: Unit ranges are from 1 millivolt to 400 volts AC/DC and 0.1 to 2,000,000 ohms. prevents “punching through” contamination or corrosion. With each of the nine resistance ranges, there is a constant current that flows through the unknown resistance. Insulation Tester (1kV below) -- 2132 IN, Clamp Meters - Designed for system use. AC Volts. The image was The Megger insulation tester is essentially a high-range resistance meter (ohmmeter) with a built-in direct-current generator.

Choose from three sensitive options for precision high resistance and low current measurements. 95X Series Hipot Testers, Temperature Indicators - Questions? The meter is battery-powered with a standard 9 V replaceable battery (included), which operates about 40 hours before the low battery indicator comes (on indicating about one more hour of battery life). Eliminates errors that affect the accuracy of low current measurements. and complies with second edition ANSI and IEC electrical safety standards • Improved sleep mode for long battery life • Relative mode to remove test lead resistance from low ohms measurements • Auto and manual ranging for maximum flexibility • Optional magnetic, Description: Accuracy is +/-2% of reading +/- 1 count. Meter connections can be via 2, 3 or 4 wires. It should be set for zero while on the conductance range with nothing connected to the terminals. Megger has models available for testing using test currents from 0.5 mA to 200 amps covering a multitude of applications that require precise low-resistance measurements. The Model HR2 meter measures resistance in nine ranges from 1 ohm to 1.9999 Tera ohms (1.9999×10 12 ohms), 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.
