Indicators
Table 6 Indicators on the HM40 Display
Symbol (s) Name Description
Battery
charge
Fresh batteries will always show three bars.
When the indicator shows two bars, the
voltage of the batteries has started to drop.
When there is a single (blinking) bar left,
you should replace the batteries. HM40 will
turn off automatically when the battery
voltage drops too low.
Alert
This indicator is shown next to the battery
charge indicator if there is a measurement
problem. The most likely cause is that the
probe is currently disconnected, or the
battery is low.
Quantity
The selected quantity is highlighted by a
light frame. The symbol on far right stands
for all quantities.
Numeric View
The Numeric view shows the currently values of
the selected humidity quantity and temperature.
In the all quantities view the font is smaller to fit
all values on screen.
