All specifications nominal or typical at +23 deg C unless noted.

Input
Strain Gages:
Quarter(120 ohms or1000 ohms and 350 ohms), half or full bridge (50 to
1000 ohms). Dummy resistors installed.

Transducers:
Foil or piezoresistive strain gage types.

Potentiometer.

DCDT displacement transducer.

Excitation
12 settings:
Variable setting: 0.4 to 6 Vdc, 0.7, 1, 1.4, 2, 2.7, 3.5, 5, 7, 10, 12 and 15
Vdc +1%, max.

Current:
0-100 mA, limited at 175 mA, max.

Regulation (0-100 mA, +10% line change):

Level:
Normally symmetrical about ground; either side can be grounded with no
effect on performance.

Bridge Balance:
Method:
Counter-emf injection at preamp; automatic electronic; dual range; can be
disabled on front panel.
