4.3 Hygrometer - Selection and Use (cont.)
Relative humidity and temperature measurements are made with the
Hygrostick, Quikstick or Short Quikstick probe, and the MMS2 instrument
uses these values to calculate a range of psychometric readings. When using
the MMS2 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.

Note: For best response time, do not store the MMS2 in excessively hot or
cold locations, such as in a vehicle.
