4. An LED indicang the measurement’s order of magnitude will be energized
G. Measurements from 1.0x10

12
ohms:
1. When the resistance measurement is greater than 1.0x10
6
ohms the test voltage will automa-
cally be increased to 100 volts, and electricaon (Test Period) is automacally adjusted to >7.5
seconds.
2. Unless there are variaons in the material or object being measured, a stable resistance mea-
surement will be obtained in approximately 8.0 seconds.

The PRS-812 can obtain an accurate resistance measurement within 2.5 seconds
up to 1.0x10
12
ohms, depending on material characteriscs. An addional 5.0
seconds of electricaon is applied in accordance with ESD Associaon S11.11
Surface Resistance Standard.
3. Once a stable measurement is conrmed and displayed by the instrument,  will be ener-
gized in the LCD and the electricaon mer will stop.
4. An LED corresponding to the measurement’s order of magnitude will be energized
H. Measurements from 1.0x10
12
to 2.0x10
14
ohms:
1. When the resistance measurement is greater than 1.0x10
12
ohms, the test voltage will remain
at 100 volts and the instrument will connue to automacally adjust the resistance range.
2. The instrument’s ELECTRIFICATION PERIOD is extended to a minimum of 15 seconds. Typically,
a stable measurement will be obtained in 15.0 to 20.0 seconds.
