Voltages
The IPS SSPM is powered by solar power and battery, which has a chargeable and a
non-rechargeable component. The rechargeable component is constantly fueled by the
solar panel. The non-rechargeable component is used when the primary battery voltage
is too low and there is not sufficient power coming from the solar panel. Once the power
of the backup battery is exhausted, it will no longer be functional. The
Voltages
menu
displays information for the power sources in millivolts (mV).
Solar Panel
voltage is the
current voltage level of the solar panel. It may be tested for proper operation by
covering and uncovering the solar panel while ambient light is available. The voltage
levels should change from a high value (uncovered) to a low value (covered). The
battery voltages
–
Main
and
Backup
- are shown separately. The values for these
voltages are shown in the following table:
Maximum

Sleep
The Sleep function allows the meter to be turned off when it is not in use, thus
conserving battery power. IPS recommends that the meter be turned off when stored or
if the meter is bagged for over 48 hours.
In order to put the meter to sleep, press OK and then press
– to confirm. This can also
be accomplished by holding down the diagnostic button until a beep is heard and the
meter shuts off.
