Operation / Handling

5 Operation / Handling
Safe and reliable operation can only be ensured provided the instrument has been installed
properly.
In order to enable precise readings, the instrument should be installed at eye level.
Note the information provided in the respective data sheets.
Ambient temperatures:
The permissible ambient temperature states within which temperature limits the gas actuat-
ed thermometer may be used without the risk of damaging it.
Within the nominal usage range compliance with the error class is ensured.
Outside the nominal usage range there will be additional temperature errors.
•
Permissible ambient temperature: -20...+60 °C (-4...+140 °F)
•
Nominal usage range: +23 ±2 °C (+73.4 ±6.4 °F)
Prevent injury and damage to property:
When erecting and operating measurement systems for hazardous, combustible, ex-
plosive substances or substances which are damaging to health, all currently valid
regulations need to be complied with.
In the case of damage to the stem in the area of the vessel, the pressurized nitrogen
helium mixture can suddenly be released.
Suitable precautions need to be introduced so as to prevent the there from resulting
risks to personnel and property.
Adjustment:
Your Precision Dial Thermometer is equipped with the possibility of pointer adjustment. After
removing the sealing screw, respectively the sealing plug on the side at the top of the casing,
a set screw at the movement will be accessible which can be actuated by means of a screw-
driver.
It is possible to correct indication errors which result, for example, through constantly devi-
ating ambient temperatures.
The correction of indication errors should only be considered provided you can crosscheck
the readout. As reference instruments you may use, for example, calibrated glass thermom-
eters or portable, calibrated digital thermometers.
The comparison of the measured values needs to be performed through measurements
•
at identical ambient conditions,
• at the same measurement location,
• at identical immersion depth,
• within a period of time during which there is no temperature change at the measure-
ment location.
