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):
+0.5 mV +0.04%, max measured at remote sense point. (Local sense: -5
mV, typical, at 100 mA, measured at plug.)
Remote Sense Error:
0.0005%/ohms of lead resistance (350 ohm load).
Noise and Ripple:
0.05% p-p, max (dc to 10 kHz).
Stability:
0.02%/deg C.
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.
Ranges (auto ranging):
+5000 microstrain (1% bridge unbalance or 2.5 mV/V), resolution 2.5
