Operation
6.3.6.1 Calibration lock
The calibration lock is used to protect parameters subject to calibration
regulations. This includes all values, which influence volume readings.
The calibration lock is designed as a button, which is positioned inside the
DL230 housing underneath the circuit board cover. It can be protected with
an adhesive label (see chapter 5.3.1.1, "Opening the calibration lock").
The calibration lock is opened by pressing the button ("P" symbol flashes in
the display) and is closed again by pressing the same button ("P" symbol
fades). It can also be closed by deleting the value "St.PL" (see chapter
6.4.6, "Ctrl." register (control)) via the keyboard or interface. Using the
configuration software "enSuite",
a time can also be set (in minutes) after which the calibration lock will
automatically close.
The level of protection can be changed for all parameters upon request,
particularly for applications, which are not subject to German calibration
guidelines.
For example, parameters, which are protected by the calibration lock as
standard, can also be protected with an administrator's lock or a certifica-
tion data log.
6.3.6.2 Certification Data Log
The certification data log is activated as standard but can also be disabled.
The corresponding parameters will then be protected by the calibration
lock.
Using the "certification data log" as per PTB-A 50.7, several parameters
subject to calibration regulations can also be adjusted when the calibration
lock is closed. This is subject to the following conditions:
•
The administrator's lock (see below) must be open.
•
There are at least three free entries in the certification data log.
The following parameters are set as default:
•
"Md.I1" to "Md.I4" modes for inputs 1 to 4
•
"V1" to "V4" Main counter for inputs 1 to 4
•
"cp.I1" to "cp.I4" cp values for inputs 1 to 4
•
"MP.I1" to "MP.I4" measurement periods for inputs 1 to 4
•
"TG.I1" to "TG.I4" daily limits for inputs 1 to 4
•
"Clr.A" delete measurement archive
•
"HTLT1" to "HTLT4" settings for HTLT conversion
For every change of a parameter listed under "PL" when the calibration lock
is closed, one row of data will be entered for the value before and after the
change.
If the certification data log is full, it can be deleted using the command
"ClCDL" if the calibration lock is open (see chapter 5.3.1.8).
