All specifications are at room temperature unless otherwise specified.
In the interest of constant product improvement, we reserve the right to change specifications without notice.
OPTIONAL VERSIONS
Optional versions have identical specifications and accessories as listed for the standard model
except where noted below. More than one option may be used.
NOTES:
[1] Verified with test data provided on supplied calibration certificate.
[2] Settling Time is the maximum time after power-up for the Offset Voltage to be /-2% of
Measurement Range output of the final offset value. Mounting surface must be at thermal
equilibrium.
[3] Half-sine pulse duration, ≥ 20 µsec.
[4] Typical.
[5] Sensitivity is proportional to excitation voltage, and at other excitation values, sensitivity can
be predicted from the 5VDC calibrated value with a small (<~.5%) increase in uncertainty.
