4.4 Start measurement
The following parameters are available when heating or cooling measurement is switched on:
• Temperature A/B
• Temperature difference
• Themal power (power)
• Thermal energy (totalized power)
To setup the display to view those parameters please refer to the display setup paragraph.
The unit for energy measurement can standard 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. To setup
the free unit go to "Measurement Setup Units ". Select the power or energy parameter,
then select "Free unit". Enter the text for the unit, then the factor for the unit entered.
The factor for energy is the amount of Joules in the free unit. The factor for power is the amount
of Watt's in the free unit.
Underneath you find a table with factors for alternative energy units.
