1. To change between ambient IN and probe OUT temperature display modes press the IN OUT button located on the back of the unit To change between displaying the memory MIN MAX and the alarm limits HI LO press the MODE button DISPLAYING F OR C To display the temperature readings in Fahrenheit or Celsius press the C F button located on the back of the unit MINIMUM AND MAXIMUM MEMORY There are four points that are automatically recorded into memory Minimum MIN Ambient Temperature Achieved Maximum MAX Ambient Temperature Achieved Minimum MIN Probe Temperature Achieved Maximum MAX Probe Temperature Achieved All four memories are independent of each other Minimum and maximum temperature memories are NOT programmable The minimum temperature recorded into memory is the minimum temperature achieved since the last time the memory was cleared The maximum temperature recorded into memory is the maximum temperature achieved since the last time the memory was cleared The minimum and maximum temperature memories are maintained over the period since the memory was cleared Minimum and maximum memories are recorded for both ambient and probe temperatures regardless of the display mode CLEARING THE PROBE OUT TEMPERATURE MEMORY 1 Select the Probe Temperature Display Mode by pressing the IN OUT button located on the back of the unit until OUT appears on the display 2 Press the MODE button until MIN2. 2 Once the above items have been manually recorded clear both the minimum and maximum temperature memory See the Clearing the Probe OUT Temperature Memory section By clearing the memory each day the minimum and maximum temperature memory will provide a record of the minimum and maximum temperature that has been achieved inside the refrigerator over the past 24 hour monitoring period The memory will also allow the user to see if the temperature inside the refrigerator went outside of the acceptable range when there was no one available to hear the alarm overnight ALL OPERATIONAL DIFFICULTIES If this unit does not function properly for any reason replace the battery with a new high quality battery see the Battery Replacement section Low battery power can occasionally cause any number of apparent operational difficulties Replacing the battery with a new fresh battery will solve most difficulties BATTERY REPLACEMENT Erratic readings a faint display no display or a battery symbol appearing on the display are all indications that the battery must be replaced Open the battery compartment by depressing the tab located at the top of the battery cover and lifting it out The battery cover is hinged at the bottom so that the battery compartment may be opened without completely removing the battery cover Remove the exhausted battery and replace with a AAA alkaline battery Make certain to insert the new battery with
3. Set a screw into the wall at the desired location Do not set the screw flush to the wall the head of the screw will need to slip into the receptacle on the back of the unit Once the screw has been properly set hang the unit in place by sliding the receptacle on the back of the unit over the head of the screw USING THE ALARM AND MEMORY TO MONITOR A REFRIGERATOR FREEZER Following is an 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 Plug the probe into the unit Install the battery Place the probe sensor inside the refrigerator Place the display outside the refrigerator Select the Probe Temperature Display mode See the Temperature Display Modes section OV EO Ne 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 6 Set the probe temperature low alarm limit to 0 C See the Setting Probe OUT Temperature Alarm Limits section 7 Set the probe temperature high alarm limit to 5 C See
