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] Individually tested to ensure compliance with specified value.
[4] Half-sine pulse duration,
≥
20 µsec.
