The ATC-125 contains the gases R-1270 and R-704
under pressure. The calibrator must under no
conditions be stored or operated at ambient
temperatures above 60C (140F). Doing so may cause
a hazard.
About the front panel:
For B versions only, the sockets on the input module
must NEVER be connected to voltages exceeding 5V
for the TC/RTD sockets and 45V for the mA/V sockets
proportional to ground. Thermostats must not be
connected to any other voltage sources during test.
About insertion tubes, insulation plugs, well and
sensor:
Never leave hot insertion tubes which have been
removed from the calibrator unsupervised – they may
constitute a fire hazard.
If you intend to store the calibrator in the optional
aluminium carrying case after use, you must ensure
that the instrument has cooled down to a temperature
below 100°C/212°F before placing it in the carrying
case.
About the fuses:
The fuse box must not be removed from the power
control switch until the mains cable has been
disconnected.
The two main fuses must be identical and correspond
to the chosen voltage.
About the liquid bath:
For liquid bath ensure that the sensor is absolutely
clean and dry as a few drops of water in the well (liquid
baths) might cause a steam explosion.
Do not pour cold fluid into a hot well – it might cause
an explosion.
