About insertion tubes and insulation plugs:
• 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 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.
