Hold Function
Press to hold the current reading and/or statistics result, and to pause statistics
accumulation. HOLD is displayed at the top-left of the LCD display. New measurements are
not displayed, trend indicators are not refreshed, and statistics are not calculated while the
hold function is active.
While the hold function is active, both automatic and manual data collection features remain
available. Both methods continue to collect real-time temperature measurements, regardless
of the measurement data displayed while hold is active.
To disable the hold function and resume normal operation and statistics data accumulation,
press
again.
Trend Indicators
Trend indicators provide a visual representation of the measurement’s stability, and
separate indicators are provided for each channel. An up arrow indicates that the current
measurement is trending upwards, while a down arrow indicates the measurement is
trending downwards. Neither arrow is visible when the measurement is stable. For best
accuracy, always allow the measurement to stabilize before evaluating or recording the
measured temperature.
Battery Indicator
Battery depletion or battery replacement will reset all measurement parameters to
their default values and deletes all existing statistics data. After battery replacement,
set measurement parameters as required.
The battery voltage indicator provides a visual representation of approximate remaining
battery life. It is located at the top-right of the
display.
The battery voltage indicator uses three bars
to represent remaining battery life. Figure 9
shows the approximate battery life for each
bar.
At zero (0) bars, the instrument will
momentarily display bATT and initiate a
shutdown sequence. To prevent disruption of
the measurement process and statistics and
data collection, the batteries should be
replaced before the battery voltage indicator
reaches zero (0) bars. See Section 2.5, Battery Installation and Replacement.
