Comfortmeter
(Thermo/Hygro) Adjustment
Comfort Meters (Hygrometer/Thermometer)
are a combination instrument, indicating both temperature and humidity.
Calibration and positioning of hands are designed to indicate perfect
comfort conditions in room atmosphere: when both hands cross in a
limited area of the dial, the COMFORT zone.
Please note: These
instructions are general, and apply to most makes -
they may not work with all. As
always, consult your owners manual or contact
the manufacturer for instructions. Results from use of
these instructions is solely at the risk of the user. Windward
Instruments is not responsible for any loss or damage as a result.
Hygrometer Adjustment:
Put damp cloth on the back of the
humidity indicator for 30 minutes (Note: you may need to remove the
instrument if mounted on a wood plaque). The scale should then read
approximately 95. If it reads a lower number or is off scale
completely, merely insert a very small screw driver in one of the slots
on the site of the movement housing closest to the Hygrometer coil and
putting pressure on the mounting bracket. Pressure from one slot will
pivot the bracket and increase the needle reading while from the other
side will reduce the reading.
For
movements that have a hole in the back of the movement housing, a
screwdriver can be placed through that hole and into the slot on the
top of the mounting bracket. Turn very slowly in the desired direction.
Merely turn the screw on the back until the pointer is on 95. The
humidity indicator will then start to operate again.
To
maintain accuracy of the instrument, it is advisable to repeat this
procedure every six months.
Thermometer Adjustment:
The dial type thermometer is of a very
solid construction and will need adjustment only in exceptional cases.
Should need occur, however, the indicator hand can be set to the
correct reading by inserting a very small screwdriver in one of the
slots on the side of the movement housing closest to the Thermometer
coil and putting pressure on the mounting bracket. Pressure from one
slot will pivot the bracket and increase the needle reading while from
the other side will reduce
the reading.
For
movements that have a hole in the back of the movement housing, a
screwdriver can be placed through that hold and into the slot on the
top of the mounting bracket. Turn very slowly in the desired direction.
