SELECTING A PARAMETER
The RHMG700DL can measure and display the value of multiple
moisture-related parameters. When the meter is in measurement
mode, you select a parameter by pressing either the
UP>
or
<DN
button to move the
▼
pointer on the top line of the LCD directly
above it. For example, at right is the display for RH measurement
mode—the operating mode that the meter enters by default when
it is powered on.
As the lower figure at right shows, moving the
▼
pointer one
position to the right (by pressing the
UP>
button once) changes the
measured parameter to AH (absolute humidity).
GENERAL CONTROLS
Changing measurement units
. By default, the RHMG700DL uses
Imperial units for all parametric readouts.
To switch to metric units
, press the
UNIT
button.
Ambient, wet bulb and dew point temperatures will then be displayed as °C rather than °F;
absolute humidity values will be stated in g/m
3
rather than in mg/L; mixing ratios will be
displayed in units of g/kg rather than GPP; and barometric pressures and vapor pressures will be
stated in KPa rather than mBAR.
Backlight
. The RHMG700DL has a green backlight that automatically illuminates whenever any
button is pressed. It will remain on for 30 seconds and then extinguish to extend battery life.
Holding readings
.
Briefly
pressing the
HOLD
button freezes both
the primary and secondary readouts.
will appear on the
display to remind you that the readouts are frozen.
To release the hold, briefly press the
HOLD
button again.
Note: When the RHMG700DL is in Hold mode, it takes two separate
presses of the
HOLD
button to power off the meter. The first
(brief) press (accompanied by a short beep) releases the hold. The
second press (and hold) initiates shutdown (announced by two short beeps).
Storing readings
. Pressing and holding the
STORE/ENTER
button for at least 2 seconds saves the
values shown on the primary and secondary readouts as a pair in the meter’s nonvolatile
memory. Each “save” automatically increases by one the Record number indicator—the number
above
MEM
at the lower left of the LCD. The readings remain in memory, available for recall, after
the meter powers off.
The next section of this manual contains instructions for recalling
saved readings.
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.
