built

in single or double storage. Clearing with adjusted time t

clear

(off;

0.01 s;

0.05 s; 0.25 s; 1 s; 5 s; 25 s), extern, via interface or automatically with the

next measuring object

Limit switches:

in parallax free thru

lens view finder,

optionally with an additional built-in laser targeting light

(max. power level < 1 mW,  = 630-680 nm, CDRH class II)

label:

according to EU directives about electromagnetic immunity

Note: The calibration / adjustment of the instruments was carried out in accordance

with VDI/VDE directive “Temperature measurement in industry, Radiation

thermometry, Calibration of radiation thermometers”, VDI/VDE 3511, Part 4.4.
