WINDOW FILTER SENSITIVITY: 0.01%, 0.1%, 1%, 10%, or full scale range (none).
READING HOLD SENSITIVITY: 0.01%, 0.1%, 1%, or 10% of reading.
TRIGGER DELAY: 0 to 99 hours (1ms step size).
EXTERNAL TRIGGER DELAY: 2ms + <1ms jitter with auto zero off, trigger delay = 0.
MEMORY SIZE: 1024 readings.
MATH FUNCTIONS
Rel, Min/Max/Average/Std. Dev/Peak-to-Peak (of stored reading), Limit Test, %, and mX+b
with user defined units displayed.

REMOTE INTERFACE

Notes:
1. Relative to calibration accuracy.
2. With Analog Filter on, add 20ppm of reading to listed specification.
3. When properly zeroed using REL function. If REL is not used, add 100nV to the range
accuracy.
4. Specifications include the use of ACAL function. If ACAL is not used, add 9ppm of
reading/°C from T to the listed specification. T
