MIN/MAX tracking. For all parameters except moisture level:
• Pressing the MAX/MIN button once displays the highest reading since entering that
measurement mode.
• 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 measurement and display of the same
parameter.
RECALLING STORED READINGS
To enter Recall mode, press the <DN and UP> buttons at the same time.
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.
To exit Recall mode and resume making real-time measurements, press the STORE/ENTER
button.
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%.
will appear at the left of the primary readout.
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 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.
