EXAMPLE - USING THE ALARM AND MEMORY TO MONITOR A REFRIGERATOR/FREEZER
Following is a simple example of how to use the alarm and memory to monitor the temperature inside a
refrigerator or freezer. This example is provided only as a helpful guide and is not intended to replace
existing facility requirements or procedures.
In this example, the refrigerator temperature must be monitored and logged for each 24 hour period
and certain actions must be taken if temperature falls below 0°C or rises above 5°C at any time during
the 24 hour period.
Unit Setup Example
1. Plug the probes into the unit.
2. Install the batteries.
3. Place the probe sensor inside the refrigerator.
4. Place the display outside the refrigerator.
Select the desired probe. (See the "Displaying Probe 1 or Probe 2" section.)
5.
At this point, if using a bottle probe, allow sufficient time for the bottle probe to reach equilibrium with
the true current temperature inside the refrigerator.
Set the probe temperature low alarm limit to 0°C. (See the "Setting The Temperature Alarm Limits"
6.
section.)
Set the probe temperature high alarm limit to 5°C. (See the "Setting The Temperature Alarm
7.
Limits" section.)
Enable the alarms. (See the "Enable/Disable Alarms" section.)
