Press Mode key (
○
2
), then press Up key (
○
4
) or Down key (
○
3
) to
set the emissivity
, then press Mode key (

) to confirm it.
The emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Mode key (
○
2
) for the
Maximum (MAX), Minimum (MIN), Different between MAX and MIN (DIF) and Average (AVG)
modes. During the measurement, the special modes reading will be displayed beside the mode icon.
