Old commands: to standardize the command structure, some old commands with numeric parameters
are replaced with new ones with hexadecimal coded. The old commands still work, but should no longer
used in reprogramming:
ms (Read temperature value, 5-digit. dec.) mw
kt1 (Read temperature channel 1) mw1
kt2 (Read temperature channel 2) mw2
qt (Read 2-color temperature, 5-digit. dec.) mw0
ez (Response time, 1-digit. dec.) et
lz (Max. value, 1-digit. dec.) lm in combination with lt
em (Emissivity, 2-digit. dec.) eg1
en1 (Emissivity channel 1, 2-digit. dec.) eg1
en2 (Emissivity channel 2, 2-digit. dec.) eg2
ev (Emissivity slope, 4-digit. dec.) eg0
aw (Switch-off level, 2-digit. dec.) ax
gt (Device temperature, 2-digit. dec.) ts
