If logged in Auto Hold, logged records will have an “H”.
If another Measure mode is selected, the Log History will reset.
If the temperature unit is changed, all logged temperature values will be automatically
displayed in the new temperature unit.
“A” denotes automatic temperature compensation.
“M” denotes manual temperature compensation.

Saving Confirmation
Enable this option to force verification of a change made
to a “GLP Data Option field” or a Sample ID name. If
Saving Confirmation is enabled, the user will have to
accept the change with a key stroke.
If Saving Confirmation is disabled, the changes made
to these fields change automatically without verification.
GLP Data
Use this option to customize log GLP information with specific identification data. When enabled, these
ID tags will be included in the GLP section of all data logs. Each data field can use up to 10 characters.
The five available fields are:
Operator ID : used to add the name of the operator.
Instrument ID : used to name an instrument with a discrete name, location or number.
Company Name : used to include the Company ID to the GLP data field.
Additional Info : two data fields are available for general notes or notations.
