How do I cold boot (reset) the HH2 Moisture Meter Readout Unit?
To cold-boot the HH2 proceed as follows:
- Disconnect the battery.
- Short out the battery connection terminals with a metal object, e.g. a screwdriver blade.
- Reconnect the battery: snap the connector in place in a single continuous action.
- While doing so, observe the display and ensure that:
a) the entire display blacks out
b) no error messages are displayed
c) the title screen ‘Delta-T Devices Moisture Meter’ is displayed.
As all volatile memory will be cleared, you’ll have to check your settings are ok (soil calibration, for example) and change if necessary. Also, if you are using a WET sensor, you’ll have to load the WET calibration file back on (see other FAQ about this).
