___________________________________________
CAUTION
The 9180, 9181, 9182, 9183, and 9476
temperature probes are not drip-proof. Water
droplets on the grip or connector may result in
malfunctions.
The 9472, 9473, 9474, and 9475 have a drip-proof
design. However, droplets occurring on the metal
terminal of the connector may cause measurement
errors.
The ends of the 9474 and 9475 sheath type
temperature probes are sharp. Be careful to avoid
injury.
To avoid breaking the probes, do not bend or pull
them.
When measuring high temperatures, do not let the
grip of the temperature probe or the compensation
lead wire exceed the temperature range (Chapter
5: Sensor (Options)).
The sheath of the temperature probe is filled with
magnesium oxide powder. If the probe is broken,
the magnesium oxide powder may spill out. Be
carefulnot to subject the sheath to excess stress.
Inhaling large quantities of magnesium oxide may
be hazardous to your health.
3.2 Connecting the Temperature Probe
Connect the optional probe.
Check the polarity of the connector, and connect
correctly.
