AC POWER SUPPLY/BATTERY POWER

The meter may be powered the following ways:

Batteries only

Typical operating time when using the three (3) each AA alkaline batteries only: Up to 1 year in display mode only, no data logging, no alarms. Up to 1 month with data logging on at a 1 minute recording rate, with no alarms. Higher capacity memory cards require more power to operate; therefore, larger cards will exhaust the batteries more rapidly.

AC power supply only

If the AC power supply is being used without batteries, in the event of a power outage, the meter will turn off and data logging will stop.

AC power supply and batteries together

Using the AC power supply and batteries together allows the batteries to act as a backup power supply in the event of a power outage.

When using the AC power supply and batteries together, the batteries will need to be replaced

periodically to insure they have suf cient power to

operate the meter during a power outage (see the “Battery Replacement” section).

MINIMUM AND MAXIMUM MEMORY

There are six points that are automatically recorded into memory:

• Minimum Ambient Temperature Achieved

• Maximum Ambient Temperature Achieved

• Minimum Ambient Relative Humidity Achieved

• Maximum Ambient Relative Humidity Achieved

• Minimum Probe Temperature Achieved

• Maximum Probe Temperature Achieved

Minimum and maximum memories are NOT programmable. The minimum value recorded into

memory is the minimum reading achieved since the last time the memory was cleared. The maximum value recorded into memory is the maximum reading achieved since the last time the memory was cleared. The minimum and maximum memories are maintained over the period since the memory was last cleared.

VIEWING MINIMUM/MAXIMUM MEMORY

Press the MIN/MAX button, the display will show “MIN” at the bottom left side of the display indicating that the minimum memory values are being displayed.

Press the MIN/MAX button a second time, the display will show “MAX” at the bottom left side of the display indicating that the maximum memory values are being displayed.

Press the MIN/MAX button a third time to return to the current temperature/humidity display (MIN/MAX will no longer appear on the display).

CLEARING THE MINIMUM/MAXIMUM MEMORIES

EXAMPLE - USING THE MEMORY TO MONITOR A REFRIGERATOR/FREEZER

Following is a simple example of how to use the Min/Max 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.

With the meter installed and monitoring the desired location, keep a notebook or spreadsheet as a manual log.

1. At the same time every day, record the following into the manual log:

• Current Date and Time

• Current Readings

• Minimum Readings

• Maximum Readings

2. Once the above items have been manually recorded, clear the memory.

By clearing the memory each day, the minimum and maximum memory will provide a record of the minimum and maximum readings that have been achieved over the past 24 hour monitoring period. The memory allows the user to see if any readings went outside of an acceptable range.

For monitoring overnight or on weekends:

1. Prior to leaving for the night or weekend, record the following into the manual log:

• Current Date and Time

• Current Readings

• Minimum Readings

• Maximum Readings

2. Once the above items have been manually recorded, clear the memory.

3. First thing upon returning from overnight or the weekend, record the following into the manual log:

• Current Date and Time

• Current Readings

• Minimum Readings

• Maximum Readings By following the above procedure, the minimum

and maximum memory will provide a record of the minimum and maximum readings that have been achieved over that time period. The memory allows the user to see if any readings went outside of an acceptable range.

DATA LOGGING FILE FORMAT/STRUCTURE

With data logging turned on (see the “Turning On/Off

Data Logging” section), the meter will write a  le to the SD memory card. The  le created is a standard text (.TXT)  le.

Once data logging has started, the  lename created

is based on the start date (month and day number) and time.

Example: Start 11/28/2013 at 16:48, will create a  le

with the name “11281648.TXT”.

The maximum size per  le is 30,000 records. During continuous data logging, once the maximum  le size has been reached, a new  le is automatically created utilizing the same  le naming method. A  le containing 30,000 records represents over 20

days of minute by minute data. Depending on the selected data logger recording rate and the duration, continuous data logging may generate numerous

 les containing data.

The  le created is a  xed width data  le that may

be read utilizing any computer application capable

of reading “.TXT”  les (Word®, Excel®, NotePad,

WordPad, etc).

The text  le is structured as follows:

Header Column Position

DATE (YYYY-MM-DD) ................................... 1-10

TIME (HH:MM:SS) ...................................... 12-20

Tair (?)1 (ambient temperature) ....................21-27

RH(%) (ambient relative humidity) ................28-34

Text (?)1 (external/probe temperature) .......... 35-44

This will show either F or C depending on the value that was selected to be displayed on the meter when data logging was started.
