The display indicates functions related to calibration of pipettes.
Pipettes calibration is related to the following functions:
−
Number of measurements
; this option enables determining number of
measurements for tested volume of a pipette (valid for each tested
volume in case of a pipette with adjustable volume),
−
Request serial number
: YES/NO. For option <YES> before starting
calibration procedure, the software displays a window and on-screen
keyboard for inserting serial number of a pipette,
−
Comply with ISO 8655
: YES/NO. For option <YES>, for tested
volumes, during pipettes calibration process the software automatically
accepts error values as specified in standard ISO 8655 (if other error
values have been accepted for a pipette, then on selecting option
<Comply with ISO 8655> the error values are neglected, and replaced by
those from ISO standard),
−
Acquire data on ambient conditions from THB module
: YES/NO. For
option <YES> the software automatically, and in specified moment,
acquires and saves ambient conditions’ parameters from a connected THB
module. If option <NO> is selected, before starting and after completing
the pipettes calibration process operator should manually insert ambient
conditions parameters (i.e. temperature, humidity and pressure in the
weighing room) from external ambient conditions sensors.
−
Result control, Tare mode, Automatic footer printout, Printout
mode, Printout
, means of using these functions is given in point 10.8.
“Additional parameters on weighing process”.
