3.11.4 Start measurement
The following parameters are available when heating or cooling measurement is switched on:
• Temperature A/B
• Thermal power (power)
• Thermal energy (totalized power)
To setup the display to view those parameters please refer to the setup paragraph of the mobalie
application.
The unit for energy measurement can be set to Joule (kilo, mega, giga), Wh (kilo, mega) or BTU
(kilo, million (MM)). In case any other unit is required the free unit can be used. Follow the setup
wizard of the mobile application to set the free unit.
First select the power or energy parameter, then select "Free unit". Enter the text for the unit of
power.Then select the W factor for the unit of power that is set in previous step.
The factor for energy is the amount of Joules in the free unit. The factor for power is the amount
of Watt in the free unit.
Underneath you find a table with factors for alternative energy units.
