is moisture proof, which thus enables the unit to be easily kept in a
clean and hygienic condition.
OPERATION
While testing the apparatus in the open air i.e. with open
electrodes check the following:
1.
Press the ON/OFF switch. After pressing the button two dashes
are displayed indicating the device readiness to work.
--
2.
Press the switch again to see the digits “1 0” indicating that
the battery is connected and the instrument operating, but no
measurement is being taken.
1 0
An additional function of the LCD display is to indicate battery failure.
When LO BAT blinks on the display you will soon need a fresh battery.
The battery is dead when the signal is constant.
The lowest scale is 10 units, while the range of measurement is from
0 to 1990 units. When this scale is exceeded the digits "1 0" appear
on the LCD display, signaling overflow (as in the case of the electrodes
being tested while in contact with the atmosphere). The range of
measurements of the detector is several times that of the vaginal
mucus electrical resistance to be tested, and in practice this scale is
never exceeded.
