Protimeter Hygromaster2 Instruction Manual
4. HYGROMASTER2 Modes
The Protimeter Hygromaster2 instrument measures air temperature, relative
humidity and surface temperature.
4.1 Hygrometer - Selection and Use
Navigate to
SELECT MODE -> HYGROMETER
and press to select the
Hygrometer
mode.
To use the Protimeter Hygromaster2 as a Hygrometer (see
Figure 4 on page
11
), connect the Hygrostick, Quikstick or Short Quikstick probe into socket
A
either directly or indirectly with the extension lead.
Relative humidity and temperature measurements are made with the
Hygrostick, Quikstick or Short Quikstick probe, and the Hygromaster2
Instrument uses these values to calculate a range of psychometric readings.
When using the Hygromaster2 to measure the conditions in air, the humidity
probe is normally connected directly to the instrument. However, when it is
impractical or awkward to use the instrument in this way, the extension lead
may be used to connect the Hygrostick, Quikstick or Short Quikstick to the
instrument. Typically, the extension lead will be used when taking readings
from probes that have been embedded in structures such as walls and floors.
