Ambient temperature: IS 50-LO plus;
IGA 50-LO plus:
IS 50-Si-LO plus;
IS 50-Al-LO plus:
0 ... 60 °C on the converter, up to 250 °C on side
of fiber and optical head
20 ... 30 °C on the converter, up to 250 °C on
side of fiber and optical head
(The laser targeting light switches off automatically if the internal temperature of the
instrument goes above 55 °C, above 70 °C at the 4 ... 20 mA output a thermo switch
sets the analog output to 0 mA)
