Maximum
The maximum value of all samples taken is stored in memory at the Record rate. This is
useful if you are looking for a high alarm while recording at a slower rate.
Minimum
The minimum value of all samples taken is stored in memory at the Record rate. This is
useful if you are looking for a low alarm while recording at a slower rate.
5.3.1.5. Channels
Only present if the logger being used has more than one channel. In the above case the User can select whether
to record both Temperature AND Humidity or just one of these. It is not possible to disable both channels. If the
radio button is checked that channel is enabled. Note – a two channel unit will record for twice as long if only
one channel is enabled.
5.3.2. Alarms Tab
The logger has alarms which are dependent on the type of logger being used. To view or set the Alarms select the
Alarms tab. This will bring up the Alarm window shown below.
This is the Alarm window from a Temperature/Humidity logger. It has two alarms per channel. The alarms are
numbered 1 and 2 for Temperature and 3 and 4 for Humidity.
Alarms can be enabled or disabled by clicking the
(ENABLED) or
(DISABLED) icons. Each click will
change the state of the alarm. In the above example Alarm 2 is disabled.
Alarms can be High or Low . Check the radio button to the left of the arrow to select. In the above example
Alarms 1 and 3 are set as HIGH alarms, Channels 2 and 4 are set as LOW alarms.
The value of the alarm can be set by clicking the text window and entering the alarm value. Note that if you enter
illegal values they will not be accepted. Also a LOW alarm cannot be higher than a HIGH alarm and vice versa.
Temperature Alarms in °F are rounded to the nearest 1° and are then converted to °C before being saved to the
logger. Similarly the alarm value is read from the logger in °C and converted to °F. This may result in a slight rounding
error which means the value entered in °F could be different to what is displayed by +1°F. This is also the accuracy of
the Alarm. The temperature engineering units can be set using the
Menu.
