Protimeter Psyclone
Thermo-Hygrometer
Instru tion Manual
INTRODUCTION
The GE Protimeter Psyclone thermo-hygrometer measures
relative humidity with psychometric measurements, along
with temperature. One button enables start, hold and OFF
operation, and four arrow keys allow you to set up and
change the measurements shown on the CD screen. An
optional surface temperature probe enables users to
determine if condensation is present. Figure 1 below shows
the Psyclone control buttons, while Table 1 lists the avail-
able parameters.

Starting the Psy lone for the First Time
The Psyclone comes with 2x AA 1.5V batteries already in-
stalled. To begin using the meter, extend the retractable
probe and press the power button. The CD screen briefly
flashes, similar to Figure 2 below. After a few seconds, the
meter changes to measurement mode and displays only
the currently selected parameters, as shown in Figure 3
below. Moisture readings appear at the top, with
temperature measurements below.
• To freeze the Psyclone at a particular reading, press the
button briefly. The “Hold” message appears to the left of
the temperature reading, as shown in Figure 2.
• To shut off the Psyclone, press the power button for 3
seconds, until the message OFF appears before the CD
blanks.
Sele ting Parameters and Cal ulations
Use the four arrow keys to select the parameters and
calculations you want to display. Press any of the arrow
keys to scroll to the parameter or calculation. The reading
changes immediately and the parameter is set once the
flashing stops. Pressing the power button instantly selects
the parameter.
• To sele t the humidity parameter (%RH, GPP or g/kg
or Dew Point):
Scroll to the top row and then to the desired parameter.
Note: If ou have selected the Ps chometric Calculation
ON option, our options include the available calculations.
• To sele t a al ulation (Minimum, Maximum or
Average):
Scroll to the middle row, and then press the RIGHT or EFT
arrow key to select the desired calculation. The
min/max/ave calculations are made from the last time the
meter was powered up. If no parameter is selected, all the
parameters in that row remain solid (not blinking) and the
Psyclone displays the current reading. Min/Max/Ave will
continue to calculate while in these modes. Push the UP
arrow to return to free measurement mode.
Setting User Options
To set up the user options to your particular requirements,
firmly press and hold the SETUP key (the DOWN arrow) for
two seconds. The lower part o the screen appears
similar to figure 4 below.
The factory default settings are:
• Temp - Off
• Psy. Cal. Options - Off
• Device auto off - 3 mins
• Back light - 0 mins (off)
Use the EFT and RIGHT arrow keys to scroll to the de-
sired option and the UP and DOWN arrow keys to set the
desired selection. Once selected, wait for the meter to re-
turn to measurement mode or push the power button to
save the change. Four options are available:
• Units °F/°C
You can display either °F or °C. (Setting °C also results in
displaying other parameters in metric units, such as g/kg.
Setting °F prompts the meter to display other parameters in
non-metric units, such as GPP or grins per pound.) Press
the UP or DOWN arrow keys to toggle between °F and °C
units.
• Psy hometri Cal ulations
You can extend the available humidity measurements to in-
clude psychometric calculations (Wet Bulb Temperature,
kcal/kg and BTU/lb shown in figure 2). Press the DOWN or
UP arrow key to turn on (or off) the Psychometric Calcula-
tion options. When the screen refreshed you can then se-
lect the desired calculation.
• Ba k Light
You can set the back light for the CD display to remain on
from 1 to 9 minutes at a time. (If you set “0”, the back light
is turned off.) Use the UP and DOWN arrow keys to scroll
to the desired number of minutes after the last button push.
• Devi e Auto OFF
You can set the Psyclone to shut off automatically after
from 1 to 9 minutes at a time. (If you set “0” the automatic
shut off is turned off.) Use the UP and DOWN arrow keys to
scroll to the desired number of minutes to stay on after the
last button push.
Using the Optional Surfa e Temperature Probe
Note: The Surface Temperature (Surface) and Temperature
Difference (Temp Diff) appear onl if ou are using the
surface temperature option.
To obtain surface temperatures via the optional probe.
1. Plug in the surface temperature probe on the right side
of the Psyclone.
2. Scroll to the bottom row using the UP or DOWN arrow
keys, and then select Surface or Temp Diff on the
screen. Selecting Ambient uses the Psyclone’s internal
sensors.
3. Remove the black cap, exposing the metal sensing strip
on the sensor.
4. Apply the metal strip on the probe to the surface you
wish to measure.
In Surface mode, the reading shown will be the surface
temperature (allow time for the reading to settle).
In Temp Diff mode, the temperature shown will be the
proximity to Dew Point (when condensation will occur). For
example, a reading of 5 degrees above the Dew Point. A
reading of -5 degrees would indicate that the surface
temperature is 5 degrees below the Dew Point and
condensation is present.
Caring for your Psy lone
• When you have finished using the Psyclone, retract the
probe back into the meter.
• Use the carrying case to shield the Psyclone when not in
use.
• Keep the Psyclone out of water and away from dirt and
dust.
• If the Psyclone has been stored in excessive heat or cold
(i.e. a vehicle), allow for increased acclimation time.
• A low battery warning appears when the battery has only
20% of it’s charge. To replace the batteries, remove the
panel on the rear of the Psyclone and insert two 1.5V AA
batteries. Do not use re hargeable batteries.

Glossary
S mbol Definition
%RH The ratio of the amount of water
vapour in the air at a specific
temperature to the maximum
amount that the air could hold at
that temperature, expressed as a
percentage.
Specific The ratio of the mass of water
Humidity vapour to the mass of dry air. For
(GPP, g/kg very low levels, the Specific
and PPMw) Humidity is also expressed as parts
per million by weight (PPMw).
DEW POINT (°C/°F) The temperature at which the air
you are measuring would be
saturated. Condensation would
begin to appear on surfaces if they
are colder than the dew point
temperature.
WET BU B (°C/°F) The temperature of a wetted
thermometer in moving air. The wet
bulb temperature is a measure of
the rate of evaporation which is
influenced by the amount of water
vapour in the air.
Enthalpy kcal/kg The amount of thermal energy
required to remove all the water
from 1kg of air and cool it to 0°C.
Enthalpy BTU/lb The amount of thermal energy
required to remove all the water
from 1lb of air and cool it to 32°F.
