NOTES
1. Reference frequency is 20 Hz on the 2 g range.
2. Over the excitation range 8.5 to 30 Vdc. Sensitivity changes
+0.1%/V typical and zero measurand output changes -0.5
mV/V typical.
3. Full scale output (FSO) is nominally 4 volts.
4. 1% is typical. 1% maximum available on special order.
5. THRESHOLD = MAX. RESIDUAL NOISE; 0.5 TO 100 Hz
SENSITIVITY
6. Per ISA 37.2 at 250 Microstrain.
7. At 100 Gauss, 60 Hz.
8. Current drain increases slightly with increasing excitation; typi-
cal change is +.06 mA per volt from 8.5 to 30 Vdc.
9. Maintain high levels of precision and accuracy using
Endevco's factory calibration services. Call Endevco’s inside
sales force at 800-982-6732 for recommended intervals, pric-
ing and turn-around time for these services as well as for quo-
tations on our standard products.
