11.2.2 Adjustment
In practice, the usage conditions during testing can vary from the measurement conditions at the
time of the factory calibration.
Due to this, the calibrator offers the facility to store its own adjustment values. It is possible to
have adjustments for user defined functions and DUTs.
The number of adjustment values can be freely selected. The calibrator can be directly aligned
to an on-site standard thermometer, therefore achieving maximum display accuracy. It is not
necessary to send the calibrator back to the manufacturer.
Note:
The factory calibration is always retained. Adjustments can be removed at any time,
resetting the calibrator back to the factory calibration.
Adjustment values can be entered:
a. In the “Configuration Range” of the main window, see Figure
16 item 9, or
b. In the DUT configuration window, see Section 6.2.4.3.
11.3 Cleaning
11.3.1 Exterior Chassis
Clean the calibrator with a dry or slightly damp lint-free cloth. Do not use sharp objects or
aggressive agents for cleaning.
Ensure that your cleaning agent cannot be a source of danger from a reaction with parts of the
calibrator or the materials inside. If unsure of clean agent compatibility, contact Druck Services.
11.3.2 Vent Grilles for Inlet Air
The grille openings, see Figure 1 items 11 and 12, in the base of the calibrator must be cleaned
at regular intervals. The cleaning interval depends upon on the air pollution at the installation site
and the amount of use.
1. Clean the grille openings by vacuuming or brushing.
11.3.3 Inserts
During normal operation, the inserts create small quantities of metal dust. This can result in an
insert getting stuck in the dry block.
1. Remove the insert from the dry block with the aid of the sleeve exchange tool.
2. Clean the insert and the dry block at regular intervals.
11.3.4 Micro Bath
Before cleaning, the micro bath must be drained as much as possible using the draining syringe.
INFORMATION
Only functions and DUTs marked with the icon can be
adjusted.
All test tasks or DUTs that use adjusted functions are affected by the
adjustment.
INFORMATION
If the vent grilles become obstructed, the thermal protection
fuse may trip. The thermal protection fuse in non-resettable. The calibrator
cannot be used anymore. The calibrator must be returned to Druck for repair.
Ensure that the grille openings are always kept clear.
INFORMATION
Before a prolonged shutdown of the calibrator, remove the
insert from the dry block or micro bath.
