Ametek JOFRA ATC-125 A

8 23-03-2009 105446 06
 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 60C (140F). 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.
