The PRS-812 Resistance Meter makes precision resistance measurements from
0.1 up to 1.0x10
12
ohms with an overall measurement tolerance of ±5%. It is
capable of measuring up to 2.0x10
14
ohms with tolerance depending on proce-
dures and condions. The PRS-812’s wide range and close tolerance make it the
ideal ESD Auding instrument for measuring resistance to a variety of ESD and
general industry specicaons. It is operated by programmed microprocessors
that control the instruments measurement process, resistance auto ranging,
test voltage selecon, electricaon periods, and display funcons. It can be
operated in either fully automac or manual modes, or a combinaon of
automac and manual modes.
The PRS-812 is unique in that it records and stores up to 80 resistance measure-
ments in its own non-volale memory register. Stored data is summarized with
a push of a buon.
Its accuracy is based on its ability to rapidly make several measurements each
second, and average them unl a stable set of eight measurements, all within
5% tolerance, are obtained. The nal averaged data is displayed as the resis-
tance measurement. Typically, measurements at less than 1 ohm are within
5% of tolerance, and those between 1.0 and 1.0x10
12
ohms are within 0.5% of
laboratory references
While quite sophiscated in design, the PRS-812 Resistance Meter is easy to use and extremely helpful in
making accurate ESD auding measurements, or general resistance and connuity checks.
