PRS-812 Resistance Meter
a. Range selecon is made in one-decade increments and indicated with illuminated LED’s.
b. For resistance ranges below <E03, use the LCD displayed decimal point (.) for seng the
desired decade. The <3 LED will be illuminated.
5. Press the Green  buon to begin the  Measurement Cycle.
a. The instrument will automacally start the Test Cycle from the selected resistance range
decade.
b. Inial Test Voltage for the selected resistance decade will be applied. For example if the 10
6
ohms decade was selected, inial Test Voltage will be 100 Volts.
c. At this point the PRS-812’s  Mode takes control of the Measurement Test Cycle:
(1) Automacally re-adjusts  in accordance with material
resisve characteriscs
(2) Automacally re-adjusts  in accordance with material resisve
characteriscs and industry standards
(3) Automacally re-adjusts  in accordance with mate
rial resisve characteriscs and industry standards
(4) At compleon of Test Cycle, displays and  nal resistance measure
ment, test voltage, order of magnitude (LED), analog scale & mulplier, and
electricaon me at end of electricaon period.
L. The Memory Register: Data Logging and Calculaon
As previously described, the PRS-812 Resistance System will acquire and store up to 80 measure-
ments, or data points, in its Memory Register when Record (REC) is acvated. Data is entered in
memory each me the RESET buon is pressed following a measurement. The data in memory can
be reviewed for its minimum, maximum and average values by pressing the RECALL buon.
1. To Acvate the Record Mode press the gray  buon once.  will be dis-
played in the lower le corner of the instrument’s LCD display.
2. To Review Data in the Memory Register press the  buon four mes, as fol-
lows:
a. 1st Press RECORD/RECALL: Provides access to data points in the Memory Register
(1) Use UP () and DOWN () arrow keys to scroll through data.
(2) You may select a data point and eliminate it by pressing . All other stored
data will shi one slot in the register to replace deleted data.
(3) Min, Max and Average of remaining data in Memory will be recalculated.
(4) Press  to proceed, or  to exit Memory Register and return to
normal operaons.
