PRS-812 Resistance Meter

Be sure to press  aer your last measurement to save it in your Memory
Register before turning the PRS-812 OFF. If the instrument is turned OFF before
pressing  the last measurement will be lost.
Good Measurement Pracces, specic Operaonal Procedures and descripons of funconal
modes are covered in detail, below.
B. Good Measurement Pracces
Several factors will aect precision resistance measurements. Most praconers are aware of the
importance of using care when handling instruments, proper use of connecons, lead resistance,
grounding, and the impact of electrical or electrostac elds on their equipment.
As with most very precise instruments, the PRS-812 circuits and its cables are sensive to the ef-
fects of electromagnec and electrostac elds. These eects are minimized by instrument and
test lead design. However, good measurement pracces should be exercised at all mes to ensure
accuracy and repeatability. Follow the recommendaons below to obtain opmal performance
from the PRS-812.
1. Instrument handling and preparaon
a. Do not drop or cause mechanical shock to your instrument
b. Store the instrument in a clean, dry environment. Do not expose the instrument to wet,
extremely hot or cold condions.
c. If the unit is stored in a cold environment, allow it to stabilize at room temperature before
powering up the unit.
d. Be sure fresh baeries are installed when beginning an extensive measurement sequence.
Periodically check the condion of your alkaline baeries by pressing . If  is
indicated, replace your baeries.

Low voltage Baeries will aect measurement accuracy.
e. When making resistance measurements below 10 ohms, perform The Low Range Calibra-
on Procedure. Repeat the procedure to conrm the instruments response.
f. During resistance measurements, stand back, away from the instrument to avoid body
capacitance or elds from eecng instrument accuracy.
g. To avoid body elds from interfering with instrument accuracy, wear a wrist strap aached
to a tested ESD ground to dissipate body charges.
