Read Types
The read type determines how the meter displays, logs and exports measurements. Ensure the
appropriate data export and data log settings are enabled in the Instrument Settings menu
before logging or exporting measurements.
· Auto-Read:
o Press the measure (esc) key to start a measurement. The AR icon blinks as the
changing value stabilizes. When stable, the AR icon stops blinking and the
measurement is locked on the display until the measure (esc) key is pressed again.
o When enabled, the stable measurement is automatically saved to the data log and
exported to a printer or computer.
· Continuous:
o Measurement values are continuously updated on the display and the Stabilizing or
Ready icon indicates the measurement stability status.
o When enabled, press the log/print key to save a measurement to the data log and
export it to a printer or computer.
· Timed:
o Measurement values are continuously updated on the display and the Stabilizing or
Ready icon indicates the measurement stability status.
o When enabled, measurements are saved to the data log and exported to a printer or
computer at the selected time interval of 3 seconds (00:00:03) to 24 hours
(24:00:00).
Stability Setting Information
The stability setting determines when a measurement is recognized as stable by the meter,
using an algorithm that evaluates measurement fluctuations. When Smart Stability is selected,
the measurement resolution is utilized in conjunction with the algorithm. Approximate mV per
minute values, estimated with ideal measurement conditions, are shown below. Values are
theoretical only and actual values will vary based on individual measurement conditions.
