#1 AUTOMATIC: RESISTANCE RANGES IN AUTO 0.1Ω TO <2.0E+12Ω as follows
@<10V: 0.1 TO <1.0E+04Ω (0.1Ω - < 10KΩ)
@ 10V: 1.0E+04 TO <1.0E+06Ω (10KΩ - < 1MΩ)
@100V: 1.0E+06 TO <2.0E+12Ω (1MΩ - <200TΩ)
#2 MANUAL: RESISTANCE RANGES IN MAN 0.1Ω TO <2.0E+12Ω as follows
@<10V: 0.1 TO <1.0E+05Ω (0.1Ω - <100KΩ)
@ 10V: 1.0E+03 TO <1.0E+09Ω (1KΩ - <1GΩ)
@100V: 2.0E+05 TO <2.0E+12Ω (200KΩ - < 200TΩ)
#3 AUTO-MANUAL: (Same as AUTOMATIC)
RESISTANCE RANGES IN AUTO-MANUAL 0.1Ω TO <2.0E+12Ω as follows
@<10V: 0.1 TO <1.0E+04Ω (0.1Ω - < 10KΩ)
@ 10V: 1.0E+04 TO <1.0E+06Ω (10KΩ - < 1MΩ)
@100V: 1.0E+06 TO <2.0E+12Ω (1MΩ - <200TΩ)
2. The PRS-812 provides three separate test voltages for resistance measurements as indicated in
the table, above:
<10 Volts
10 Volts
100 Volts
In and modes the instrument automacally controls volt-
age and resistance range based on resistance characteriscs of materials being measured. In
the mode the operator may select test voltage and and resistance range. Note that
the most ecient mode of operaon in for maximum baery life.
