Data log any parameter measured by a fieldpiece accessory head

Unique Features:

• Record data points manually, automatically or trigger to log outside a range.
• Real time clock: second, minute, hour, day, month and year.
• All data points are time stamped.
• Multiple data sets of various parameters can be stored.
• Easy download to PC.
• Cost effective, multi channel recording using multiple DL3s.
• 20,000 data points.
• Combine with the AAV3 anemometer to determine CFM easily.
• Long battery life.

New Upgrades:

• TRIG (trigger) switch position. Set DL3 to record only the data needed.
• Enhanced data scroll.
• Bright, blue backlight.
• Export data in .xls format

Using Fieldpiece accessory heads to record.

1. RH%, temp, wet bulb, dew point, temp difference, air velocity.
2. CO ppm, %O2 in air and %CO2, all of which are products of combustion.
3. Gas pressure, static pressure, differential pressure.
4. Subcooling, superheat, pressure (hi-side or low side).
5. AAC/ADC, VAC/VDC, mA and µADC.

How it works:

Set up the data logger to record for your desired length of time and at your desired frequency. Record. Then either read the results on the DL3 or download the information to a computer.

ARH4 on DL3:

SPAN

PER

MULT

+ TRIG

mVDC

200

1. Set SPAN, or how long you want to record data. Data can be recorded from 1 second to once every 999 hours.

2. Set PER, or period. PER is how often you want to record data. Data can be recorded from once a second to once every 999 hours.

OR

2. NEW: Set TRIG or trigger. Use TRIG to set DL3 to record only data points that fall fall outside a pre-set range you define

3. Set MULT. This is for accessory heads that require you to move the decimal

4. Set dial to appropriate mV range and the reading will be displayed in LCD.

To begin recording, press START. At any time, you can press RECORD to add a data point, complete with real time stamp. A new data set is started when the rotary dial position is changed. Previous data sets are maintained untill the DL3 is cleared.

To view results, select READ/SEND, press MIN/MAX/AVG to see min, max and average. Press and to scroll through the data or to change data sets

Download, format, graph and print the data recorded. All formatting is done in Excel

Easy CFM measurements:

Take an average of the air velocity by taking a number of readings and then averaging them by pressing the MIN/MAX/AVG button.

To get CFM just multiply by the free area.

Using Multiple Data Loggers:

A common customer complaint  is “The system runs all the time”. With multiple DL3s you can  determine if the system is running all the time, as well as

Troubleshoot the cause of the problem. Put one DL3 with an ACH4 on the condenser to log amperage to track the time when the system is running and how hard. At the

Same time, log indoor temperature by using the DL3 with an ARH4 to see if the target temperature is being reached and if the system is performing as it should.

Below: By downloading the data from two DL3s into a spreadsheet you can analyse it, line up the times, format the data and perform mathematical operations. You can graph it too, all formatting is done in Excel.
