A. Overview of PRS-812 Operaon & Measurement Test Cycle Sequence
The following 10 points provide a general overview for calibrang and using the PRS-812 for resis-
tance measurements.
1. Slide Baery Buss Cut O switch to 
2. Press Red buon once to power up PRS-812
a. Instrument performs circuit check, and tests LED’s, LCD display, and baery voltage.
b. LCD displays  if baery voltage suitable for instrument operaon; displays  if bat-
teries require replacement
c. Instrument ends startup sequence in default , Exponent Display Mode 1.0EXX
3. Select Funcon Mode if other than , Exponent Display Mode 1.0EXX is desired by press-
ing  buon
4. Perform low resistance range calibraon aer 3 minute instrument warm-up, if desired
a. Install Calibraon Shunt between posive (+) and negave (-) terminals
b. Press  then  within ½ second
