TBN581 (ORP/pION) TRANSMITTER
CALIBRATION
L - 6
Bench Calibration (ORP/pION)
This procedure applies to TBN581 Transmitters configured for either
ANALOG
or
DIGITAL
. Any differences between the two are noted in
the
Comments
column.
Value from last calibration. If
NEW SENSOR
, effi-
ciency will be 98%. This value can be changed if
desired. A change in efficiency will affect calibration
span.
This value is recalculated during each calibration.
This value shows the offset change over time for a
particular sensor. Value resets to 0.00 pH if installing
a new sensor.
