MIN/MAX tracking
. For all parameters except moisture level:
• Pressing the MAX/MIN button once displays the highest reading
since entering that
measurement mode.
will appear at the left of the primary readout.
•
Pressing the button twice displays the lowest reading
since entering that measurement
mode.
will appear at the left of the primary readout.
•
Pressing the button a third time resumes real-time measuremen
t
and display of the same
parameter.
RECALLING STORED READINGS
To enter Recall mode
, press the
<DN
and
UP
>
buttons at the same time.
will appear
above the Record number indicator at the lower left of the LCD. The Record number indicator will
correspond to the last pair of readings stored.
You can now use the
<DN
and
UP
>
buttons to navigate to and display a specific pair of readings.
For example, the screen shot below shows that a pair of readings of 63.8% for RH and 28.8°C for
temperature were stored in Record location 08.
Alternatively, you can repeatedly press the
UP>
button to recall all
readings in the order in which they were stored, or the
<DN
button to
recall them in reverse order. Pressing the
UP
>
button when the last
stored pair of readings is displayed returns the Record number
indicator to 01, corresponding to the first pair of readings stored.
Pressing the
<DN
button when the first stored pair of readings is
displayed returns the indicator to the record number of the last pair
of readings stored.
To exit Recall mode
and resume making real-time measurements, press the
STORE/ENTER
button.
To erase all stored readings
, press and hold the
ZERO
and
UNIT
buttons at the same time for at least 2 seconds. The meter will
respond by sounding three short beeps and resetting the Record
number to 01. You can clear all stored readings while operating in
Recall mode or Measurement mode. Clearing the memory in Recall
mode produces the display at left.
SETTING ALARMS
The RH650 allows you to set alarms that will repeatedly sound the beeper if the measured RH
level or the moisture level of a material (measured by either the pinless or pin-type sensor) is
above or below a certain value. The upper and lower limits are called alarm setpoints. For
example, the screen shot at the top of the next page shows that the upper limit for RH—the
HIGH
setpoint of the RH alarm—has been set to 63.8%.
