Fieldpiece DL3 User Manual
Two ways to connect to your
Fieldpiece accessory heads
The DL3 is designed to connect to Fieldpiece
accessory heads by simply attaching them to the top
of the Data Logger (1). You can also choose to connect your Fieldpiece head remotely through our
adapter handle, Fieldpiece part # AHDL1 (2). For
most heads, move dial to the
appropriate mVDC range (1).
For the AAC clamp (ACH4),
move dial to the appropriate
mVAC range (2). For 200mV to
2000mV, select the 2000mV
range on mVAC or mVDC.
Symbols used:
Caution, refer to manual.
Attach to Fieldpiece access. head
To use the DL3, you need a Fieldpiece accessory
head. Fieldpiece offers heads to measure many different parameters. Below are just a few of the options
you have, visit www.fieldpiece.com for all the currently available accessory heads.
±Trigger
Select the Hi or Lo trigger by pressing the S or T
buttons, press ENTER to change the Hi or Lo triggers. Use the W and X to change between digits and
the + and - sign, use the S and T to change the values for the digits. Press ENTER to lock in the
changes for the Hi or Lo trigger. The triggers will
remain in the memory until the meter is turned to the
OFF position. Once a trigger is set, avoid rotating the
dial through the OFF position so as not to clear the
trigger.
Record outside a band
To record outside a band set the Hi trigger above
the Lo trigger. For example, set the Hi trigger to 90.0
and the Lo trigger to 10.0. The DL3 will only record
readings that are higher than 90.0 or below 10.0.
For your safety...
Disconnect everything from meter before opening
the case. Work with others. Turn off power to the circuit under test before cutting, unsoldering, or breaking the circuit. Do not apply more than rated voltage
between input and ground.
Maintenance
Clean the exterior with clean dry cloth. Do not use
liquid.
Battery replacement: When the multimeter displays " " the batteries must be replaced or readings will be off and won’t save correctly, if at all. Data
in memory will be maintained while changing batteries. Disconnect and unplug head, turn meter off, and
remove the battery cover. Replace the batteries with
1.5V AA batteries.

DL3 Data Logger
The DL3 data logger records mV signals from any
Fieldpiece accessory head. It has an internal real
time clock. Program automatic recordings using
SPAN (the time over which measurements are made)
and PER (time period between measurements). The
new TRIGGER feature allows the DL3 to start and
stop recording points when the data is oustside of a
specified range thereby only recording the data that
is meaningful to you. Manually add single measurements by pressing record. You can readout the data
from the LCD screen using MIN/MAX/AVG and arrow
buttons, or you can send the data to a personal computer with a USB port to view as a spreadsheet.
Data sets
Create a new data set by changing the rotary dial
position outside of the measurement scale of the previous data set. Each data set has a MIN/MAX/AVG
and one PARAM (parameter) label.
Start button
Begins the programmed recording defined by
TIME, SPAN, PER, PARAM, TRIGGER and MULT.
Available only when an input range is selected
(200mVAC, 2000mVAC, 200mVDC, or 2000mVDC).
Stop button
Use to stop recording. Pressing Start resumes
recording in current data set. Only changing dial position terminates data set.
Backlight
Press backlight button for the blue lighting of the
display. Will automatically turn off after approx. 60
sec.
Record button
Press to insert a single measurement to the cur-
rent data set. If you are in the middle of a programmed recording, the single measurements will be
entered into the data set according to the time it was
taken.
Clear button
Use to clear saved data. This function is only avail-
able when on READ/SEND range. Press CLEAR and
use W and X to select N(o) or Y(es). Press ENTER
to confirm choice.
Rotary dial functions
TIME
Use to set time of day. Press ENTER, select min-
utes, hours, days, month, and year with W and X.
Change value with S and T. Press ENTER when
finished.
SPAN
Use to set span of recording. Press ENTER, select
unit of time (Sec, Hr, Min, D) with W and X, and
adjust number with S and T. Press ENTER when
finished.
PER (Period)
Use to set time between readings. Adjusting Per is
identical to adjusting Span.
PARAM (Parameter)
Use to label readings. Press ENTER, select posi-
tion to change with W and X. Select character with S
and T. PARAM is the “Type” column in the .xls file.
MULT (Multiplier)
Use to set value to multiply data when uploading to
computer. Press ENTER, select multiplier or divisor
with S and T. Press ENTER when finished.
READ/SEND
Use to read saved data. Press the MIN/AVG/MAX
button to read minimum, average, value of current
data set. Use S and T to scroll through readings.
Use W and X to change display of data descriptor (#,
date, year). The DL3 has wrap scrolling, press up on
#1 takes you to the last date point saved. Hold down
the UP and DOWN arrow to scroll faster.
Also used to transfer saved data to a PC. Press

Use data to create tell-all charts
The chart on the right was taken directly from the
data sent from the Data Logger. Once saved, you
can open the file with any spreadsheet supporting
.xls format, including Microsoft Excel, and edit any
way you like. The chart on the right is exactly how it
looks after placing into a spreadsheet, adjusting column width to fit, and adding borders to the cells.
The sheet has 6 headings. The Reading heading
is the mV value recorded. The X1 is the value you
select as the MULT. The Type is the PARAM you
select to label the reading. The MAX/MIN shows the
maximum and minimum reading for that data set.
The AVG heading shows the running average for that
data set. A new data set is created when the rotary
dial position is changed.
The DL3 can be used to make reports showing a
wide range of applications all on one chart. In Data
Set 1, 10 temperature readings were taken using the
Sling Psychrometer Head (ARH4). You can just
leave it on its own taking measurements at any interval, here every hour.
Data Set 2 shows how the DL3 can be used with
the Anemometer Head (AAV3) to take a 3x3 reading
of a ventilation hood. These were manual recordings.
Notice here how the PARAM was changed to f/m to
represent feet/minute and the MULT was changed to
X100 to let you know the readings were multiplied by
100. Each accessory head will say in its instructions
whether or not the value recorded needs to be multiplied and what to multiply by.
Data Sets 3 through 7 show how, when you need
to record multiple parameters to evaluate a system,
you can just take a reading, change the PARAM, and
each measurement will be shown in its own data set
with their own label (PARAM) since they aren’t related. These five parameters were part of an air
conditioning system evaluation. Here, the user chose
outdoor air temp to be represented by oFa, wet bulb
as WB, suction line temp outside as STo, suction line
temp inside as STi, and liquid line temp as LLT.
These are just arbitrary labels. Set them to whatever
makes the most sense for the job you’re doing.
