Allow the bath to cool down before switching the bath off and on to resume normal
operation. Note that if the cause of overheating is an incorrect set point, this will need to
be corrected otherwise the alarm will operate again.
You should set the over temperature value, allowing for a safety margin to the sample
maximum temperature limit if possible. Additionally the limit should be greater than
the bath set point to avoid nuisance alarms. Grant recommends this is at least 1°C.
To set the over temperature alarm:
Figure 4 - Setting the over temperature alarm
To disable the alarm, set the over temperature alarm limit to 10.0°C and then press the
down button one further time so the display shows . Save this by pressing the over
temperature alarm key.
7.3.5 Configuring and running temperature presets (, ,)
Temperature presets allow you to conveniently store bath temperature settings you
routinely use. The bath has 3 presets, numbered 1 to 3.
You can set the bath to the value stored in the temperature preset by pressing the preset
button you require, followed by set.
Before you can use presets you need to store the values you wish to use in at least one
of the presets using the following sequence:
The OTA is now set and the
bath will display the current
water temperature
Set the value you wish to
use – in this case 40ºC
If an over temp value has
already been set the display
will show the value and not off.
