1)
Selecting √2 current multiplier
This option increases current through the probes by √2 (double-power), to determine any probe self-heating. The best method of using this option is
first to let the sensor reach a steady temperature and note the value. It may take some time to stabilise. Note the value down.
Press
[√2]
the probe will increase the heating effect on the probe, and the value displayed will represent the temperature due to the increased
current. When the reading has stabilised, note the temperature and calculate the temperature change.
2) The selected input channel is interrogated before each measurement cycle, and when enabled, SMART probes are identified by ‘SMART´ appearing
as (S) beside the field
[√2]
. Open circuit thermometer input channels will display nothing, the symbol “OL” displays that the measurement value is out
of range.
