Dryer Control:
•
Autostart:
Analysis starts as soon as the lid is closed (no pressing of start key)
•
Quickstart:
Initial weight is taken as soon as the start key is pressed or in case of autostart the lid is closed
without waiting for stable weight. Quick start is recommended for samples with easily volatil solvents
•
Refill:
The lid can be opened within the analysis to apply drying additives (solvents). Gain of weight is not
taken in account.
CheckWeigher:
Set the limits for your weighing in (see below)
Ash Residue: Off
, On
Allows the calculation of ash after exern ashing of sample. (see below)
8.1.1 Interval:
Interval: Off
, On
Enables or disables the current interval for the drying. This is only available in Interval 2 and Interval 3.
Temperature (50-230 °C)
The drying temperature can be entered in 1°C increments from 50 °C to 230 °C.
Heating mode:
•
Standard:
The drying temperature is predefined by the user. The end temperature is started up with a high
heat output and is kept constant.
•
Boost:
for samples with a very high moisture content (e.g. liquids).
The drying temperature is predefined by the user. During the first minutes of drying, the target temperature
is exceeded by 40%. The time is selectable between 0.1 - 10.0 min. Once this time has elapsed, the tem-
perature is adjusted down to the target temperature. The maximum temperature reached during the boost
is the highest definable temperature of the moisture analyser.
•
Ramp:
for samples with a low moisture content in which there is a risk of combustion.
The drying temperature and the ramping time (5-20 min) can be defined by the user.
Stop time:
Fixed time after which the analysis is stoped.
Stop mode:
End-point conditions for stable weight(switch-off criteria).
•
Delay time:
The stop criteria is only taken in acount after the delay time. This might be an option when
moisture of different boiling points are present in one sample.
•
Digit/Time:
The drying procedure ends as soon as the reduction in weight, during the time set, is smaller
than the number of digits set. The reduction in weight must have been greater than the end-point condition
at some point. Note: d is depending on the chosen resolution (Standard (d=1 mg), heigh (d=0.1 mg))
•
Percent/Time:
The drying procedure ends as soon as the reduction in weight, during the time set, is smaller
than the percentage set. The reduction in weight must have been greater than the end-point condition at
some point. Percent is based to the weighing in.
•
AdaptStop:
Is a fully automatic stop mode which determines the switch-off time on the basis of the drying
progress.
•
Minimum stop:
The drying procedure ends as soon as the dry weight in % (100 % .. 0 %) drops below the
set minimum.
