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.

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.

ALARMS

Independent High/Low alarms may be set for all readings (ambient temperature, relative humidity and probe temperature). Temperature alarm limits may be set in 0.1° increments. Relative humidity alarm limits may be set in 0.1% RH increments.
