High Resistance Meter
HR2
The Model HR2 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 sample. 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. Note that resistance in units of T ohms is the inverse of conductance in pS, so that the resistance can be calculated from the conductance. For example, 100 pS is 0.01 T ohm (10 G ohm), and the highest readable conductance of 199.99 pS is essentially 5 G ohms.

High Speed DC Electronic Load
6330A series
The 6330A family offers 8 types of modular loads with power ranging from 30 watts to 1200 watts, current from 0.5mA to 240A, and voltage measurement from 0.5mV to 500V. Each load is isolated and floating, programmable in dual current range and measuring voltage range, and capable of synchronizing with other modules for control operating. The load can be operated in constant current, constant voltage, and constant resistance. With Synchronic parallel control capability, 6330A series loads allow users to parallel and synchronize more than one load together from an internal loading control signal. This feature provides synchronic dynamic loading test for multi-output power and high power test solution. Real time measurement of voltage, current, is integrated into each 6330A load module using a 16-bit precision measurement circuit. The user can perform on line voltage measurement and adjustment, or simulate short circuit test using the simple keypad on the front panel.

High Voltage Tracking Resistance (HVTR)
UL 746A
The High Voltage Tracking Resistance (HVTR) test method is used to assess the susceptibility to tracking of insulating materials that are exposed to high voltages outdoors. Insulators installed in the open are often at the mercy of humidity. Their electrical insulation properties can deteriorate to such an extent as a result that tracking paths are formed on the insulator surface. This test determines the tracking resistance that defines the dielectric strength of the insulating material surface and the maximum allowable leakage current (tracking).
