JUMO 60.8425 Contact dial thermometer with inductive contact Operating Manual - Handbuch (Seite 20)

Ambient
temperatures Dial thermometers exhibit the highest measurement accuracy at an ambient
temperature of +23°C at the case and capillary. Other ambient temperatures
will lead to indication errors. The corresponding influence on the case or
capillary and the permissible ambient temperatures for storage and transport
can be taken from the appropriate data sheet.
Nominal
operating
position unrestricted
Arrangement of
the capillary ❏ The capillary should not be run close to sources of heat or cold.
❏ Protect the capillary from possible damage.
❏ Kinks or breaks in the capillary will disable the thermometer.
Minimum bending radius: 50 mm
❏ If the probe is subject to shock or vibration, the capillary should be
arranged in several loops between the last fixing point and the probe, so
that it can swing freely.
Probe
installation The thermometer probe must be so
installed that its active portion (marked
length L) is completely immersed in the
medium to be measured, otherwise a
measurement error will occur.
When deciding on the thermometer probe
location, the temperature distribution in the medium has to be taken into
account.
2.5 Operation
Setpoint
adjustment Setpoints can be adjusted by turning the knob in the center of the window.
With version “Setpoint adjustment by key”, the setpoints can be adjusted
through the adjustment lock (key is with the terminal box).
Indication
correction If the ambient temperatures at the case and capillary deviate from the
calibration temperature (+23°C), there is a permanent error at constant
ambient temperatures, or a variable error under changing ambient
temperatures, see Installation / Ambient temperatures. Dial thermometers with
indication correction can be adjusted at constant ambient temperatures. The
adjustment is made on the back using a screwdriver.
