Resistance Measurements under 0.10 ohm (PRS-801B only)
The meter is capable of making very low resistance measurements. For measurements with the PRS-
801B that are under 0.10 ohm, follow these steps:
1. Press and hold for 2 seconds to turn the meter ON.
2. Press to select MANUAL modes.
3. Using the 800PSL and 800TVL Test Leads, you must null the leads resistance (see Null
Adjustment for Lead Resistance for instructions).
4. Make sure to ground the green lead of the 800PSL to earth ground.
5. Press . The meter will begin measuring.
Resistance Measurements 1.00E+12 (PRS-801B only)
The PRS-801B is a wide range resistance meter capable of making measurement up to 2.00E+14.
To get the most accurate measurement in those ranges, the Electrification Period is extended from 15
seconds to 60 seconds in those ranges. This allows the meter to stabilize and find the most accurate
measurement.
Many factors may affect stability in those ranges. Here are some considerations when making
measurement greater than 1.00E+12 ohms:
 The electrification period need to be extended to 60 seconds or greater.
 Use the meter in CONTINUOUS mode and observer the display for stable measurement.
 Make sure the operator is grounded via ESD footwear/flooring or using a wrist strap.
 Use the Prostat 800PSL and 800TVL test leads.
 Minimize contact of the test leads with grounded surfaces.
 Remove all unnecessary static generators
