Input configurations |
1, 2 & 4 arm strain gauge networks. |
Resistance of Strain gauge |
Nominal 120 Ohms, 350 Ohms and 600 Ohms in 1, 2 & 4 arm active networks and other values in 2 & 4 arm active networks. |
Bridge balance |
Ten-Turn Potentiometer permits to get bridge balanced against difference in
gauge resistances upto 1.5%. |
Bridge selection |
Manual by digital selection switch. Auto by scanning system with the time interval between channels adjustable from 5 to 180 secs |
Calibration and Compensation Facility |
A Calibration switch and circuit is provided either to compensation facility calibrate or to compensate a preload. This circuit produces signal equivalent to +/ - 10000 microstrains. This facilitates the user to study very small dynamic strain over and above large static strain leve1. |
Bridge excitation |
Approx 5 Volts DC Stabilized. |
Gauge factor adjustment |
l.5 to 4.5 continuous. |
Indication |
Digital Panel Meter |
Power supply |
230 Volts 50 Hz AC Mains. |
