Useful Modes of Operations |
Auto Mode |
The instrument automatically selects and adjusts test voltage, resistance range, electrification period, then displays and Holds the
measurement. The displayed measurement is the average of eight consecutive measurements, all within ±5% of each other. The measurement is “saved” in the Memory Register by pressing
RESET. The instrument is now ready for the next measurement. |
Manual Mode |
Allows operator to select resistance decade, test voltage and electrification period (EP). |
Automatic Manual |
Same as Auto Mode with following exceptions:
- Allows operator to select starting resistance decade
- Always starts measurement from the last measurement value without resetting to zero. This extends battery life & speeds up measurement sequence. |
Data Log & Calculation |
In RECORD mode, the PRS-801 stores up to 80 measurements, and on demand will calculate and display the Minimum, Maximum and Average measurements
stored in the register. Using its RS-232 output and cable accessory, the PRS-801 will communicate with computer serial ports. The instrument is supplied with the
new PROSTAT® Audit Program on a 3-1/2 inch disc, which contains spread sheet templates for recording ESD Audit Program Data in Excel® software. The
PRS-801 computer output and Program disk are compatible with the Semtronics SCCN® ground monitoring system. |
Usage Recommendation |
