DESCRIPTION
The Series 8159 is a microprocessor-based digital indicator capable of interfacing directly to low
level strain gage transducers. An internal, high gain, fully differential amplifier and a 4-½ digit
analog-to-digital converter combine to accurately digitize the input signal. A 5V @ 60mA or
10V @ 120mA, short circuit protected, transducer excitation supply is also provided. A +/-
10VDC analog output signal, with a 1kHz bandwidth, comes standard with the instrument. A 4-
20 mA analog output signal is also standard with the instrument. A front panel RCAL switch
provides a convenient calibration feature. TARE and CALIBRATION are easily performed via
front panel pushbuttons.
