31 MAX MASS LIMIT 0
This limit applies to all possible mass entries. Exceeding this limit prevents a mass from entry. The
default limit is 1.5g
30 MIN MASS LIMIT 0
This limit applies to all possible mass entries. An entry below this limit will be rejected, the default is
0.2g.
21 MISFIRE LIMIT 1
If the sample is not igniting then it is called a misfire. The unit checks the temperature rise 30 seconds
after firing, and if the rise is below the limit a misfire is declared and the process is terminated. The
default value is 0.44C. The misfire limit checking can be disabled by entering zero.

TIME AND DATE
The CAL3K units have a date and time circuit which keeps the time. The data and time are attached to
every calibration, result and event. The following command set the time and date:
4 TIMESET HH:MM:SS 1
This command sets the time in HH:MM:SS. The internal clock runs for about 1 week without power and
then the time (and date) must be set.
5 DATESET YY:MM:DD 1
This sets the date of the CAL3K internal real time clock. Note that the clock remains life up to a week
without power. The entry is the form:
YY/MM/DD
The date can be used as a Group Identification (GID). This is not available on the
CAL3K-S.
122 DATE IS GID 1
This YES/NO entry allows for replacing the GID with the DATE in the form YY/MM/DD. The GID (Group
Identification) is attached to every sample recording. Note that the first 8 characters of the GID are left
blank.
The time can be used as a Sample Identification (SID). This is not available on the
CAL3K-S
. When this
feature is enabled then the auto-increment of the SID is disabled.
121 TIME IS SID 1
