Datalogger Operation
Note: The Heavy Duty Meters have an Auto-Shutoff feature that automatically turns off the
meter (after 10 to 30 minutes depending on the model). This feature should be disabled
during a datalogging session. Press the ‘RECORD’ button on the meter to disable the Auto-
Shutoff feature.
Automated Datalogging Preparation
This function permits the Datalogger to automatically collect readings at the sample rate
set by the user.
1. Connect the Datalogger's IN port to the Heavy Duty Meter as shown in the
illustration. (The supplied cable connects the Heavy
Duty meter to the Datalogger). Use the Isolated or
Direct (non-isolated) port on the Datalogger as desired.
2. Turn the Datalogger OFF (‘0’ switch position).
3. Slide the Auto/Man/Out switch to the Auto position.
4. Slide the Time switch to the ‘S’ (seconds), ‘M’ (minutes)
or ‘H’ (hours) range position depending on the data
sampling rate desired.
5. If this is the first time the datalogger is being used,
reset (erase) the datalogger's memory per the Reset Function section below.
6. Power the datalogger (slide switch to the ‘I’ position).
7. To set the sample (recording) rate, press and hold the SET button and, while holding
the SET button, press the INC 1 button to adjust the units digit (use the INC 10
button to adjust the tens digit). Release the SET button when complete. You can set
the interval from 1 to 99 seconds, 1 to 99 minutes, or 1 to 99 hours.
Note: Always set the AUTO and TIME switches to the desired setting before turning
on the Datalogger.
Begin Automated Datalogging
1. Press the PAUSE button to begin logging measurements. The PAUSE LED will
switch off and the DATA LED will blink each time a measurement is recorded.
2. Press the PAUSE button a second time to pause datalogging (PAUSE LED lights).
3. Use the PAUSE button to toggle recording ON (resume) and OFF (pause). When
datalogging is resumed, new readings are recorded right where the datalogger left
off so that readings are not overwritten.
RESET Function
The RESET function erases all of the stored Datalogger readings.
1. Connect the datalogger to the meter as previously described.
2. Set the Auto/Man/Out switch to either the AUTO or MAN position.
3. Power the datalogger and the meter.
4. Press and hold the RESET button for approx. 4 seconds, until "00" is displayed.
NOTE: It may take up to three RESETS to clear all the datalogger memory levels. To be
sure, repeat the RESET procedure three times in succession.

FULL Indicator
The FULL indicator lights when 7999 data points have been recorded.
NOTE: Data will remain in memory until the Datalogger is RESET (see previous section) or
until the batteries are removed.
Manual Datalogging
Manual datalogging allows the user to record one reading at a time.
1. Turn the Datalogger OFF (‘0’ switch position).
2. Slide the Auto/Man/Out switch to the MAN position.
3. Power the Datalogger (‘I’ position). Note that it is very important to set the MAN
switch before turning the Datalogger on.
4. Press the PAUSE button to log one measurement.
5. When the Datalogger memory is full (7999 readings), the FULL indicator will light.
6. To erase (reset) the Datalogger memory, refer to the Reset Function section earlier
in this manual.
Transferring Data to a PC
Once data is collected, the next step is to connect the Datalogger to a PC and transfer the
collected readings.
Hardware Connection
Connect the Datalogger’s OUT port to the PC COM
port as shown via the supplied cable (3.5mm phono
to DB-9 cable). Use either the Isolated or Direct (non-
isolated) output port.
WindowsTM Datalogger Software
Install the supplied software from the WindowsTM
program CD-ROM using the instructions provided on
the CD-ROM. The following software screen will
appear.

Begin Data Transfer
To transfer data from a Heavy Duty meter to a PC, follow the instructions shown below:
1. Slide the Auto/Man/Out Datalogger switch to the OUT position.
2. Power the Datalogger.
3. Select COM 1 or COM 2 on the software screen.
4. Type a file name in the Data File Name field on the software screen.
5. Click on the START key in the software window
6. Press the RESET button on the Datalogger to begin the data transfer.
7. The DATA LED will rapidly blink as the data transfer takes place.
8. Press the PAUSE button to halt the transfer.
9. When the Data LED ceases blinking, the data points have been transferred.
10. After the data points have been transferred, turn off the datalogger. Data will
remain in the datalogger as long as the batteries are fresh.
The data points are transferred to the file named in step 4 above. To view the transferred
data, click the VIEW DATA button on the software screen. The file stored on the PC can
now be opened in other applications such as spreadsheet, word-processor, database or
graphics programs.
Battery Replacement
When the Battery Status LED indicator is NOT lit the batteries should be replaced. Slide
the rear battery cover off in the direction of the arrow. Replace the four ‘AA’ batteries and
secure the battery compartment cover.
