Model: HR2

The High Resistance Meter measures resistance in nine ranges from 1 ohm to 1.9999 Tera ohms (1.9999x1012 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 sam ple. Basic accuracy is +/- 2% of reading +/- 1 count. 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 faster to their final value on conductance (usually under one second), than on resistance (several seconds), and conductance is also capable of detecting higher resistance than the resistance ranges can.

Resistance ranges are 19.999 K ohms (minimum digit represents single ohms), 199.99 K ohms, 1999.9 K, 19.999 M, 199.99 M, 1999.9 M, 19.999 G, 199.99 G, and 1999.9 G ohms. The single conductance range is 199.99 pS. There are two offset controls; one control sets the "zero" for resistance, which is determined while the terminals are shorted together. When set correctly, all nine ranges will read zero, and this control will generally never need to be altered.
