Note: The DLPT2+ will automatically switch OFF
after approximately 1 minute if no keys are
pressed.
Note: When a key is pressed to initiate a test
sequence, the DLPT2+ will compare the type of
appliance connected with the test sequence that
has been selected, and where possible, will
prompt the user if an inappropriate test has been
selected.
For example, if an IEC lead is connected
between the front panel mains socket and the
IEC socket on the end panel and a CLI appliance
test is selected, the DLPT2+ will flash the Cord
test enunciator to indicate that the Cord test is
the most appropriate test.

3 Performing Tests
Press CLI and CLII keys simultaneously to switch on
the DLPT2+. When the unit is ready the display will
be as shown below.
Operating Instructions
3.1 Checking a mains power outlet
Connect DLPT2+ mains lead to the mains inlet
socket and to the power outlet to be tested.
Each time mains voltage is detected, the lineneutral, line-earth and neutral-earth voltages will be
displayed for 2s as shown below.
If the voltages are within the acceptable limits
shown below, a tick is shown next to the enunciator.

After 2s the display will return to the start up screen.
If the mains voltage is incorrect then the DLPT2+ will
remain in voltage mode until the voltage is corrected
or removed.
3.2 Testing a Class I Appliance
• Visually inspect the appliance and mains cord

• If the measured value is less than the factory set
pass/fail threshold, the measured value is
displayed and the unit indicates a pass result, as
shown below.
Operating Instructions
Note: The DLPT2+ can perform a continuous Rpe
measurement (max 3 minutes). Press and
hold the CLI key for approximately 5s until
the unit emits a beep and the symbol
appears on the display. The DLPT2+
continuously displays the current
measured value on the display and stores
the maximum value in the memory. By
pressing the CLI key again, the
measurement is repeated with reversed
polarity. Press the key again to terminate
the Rpe test and display the maximum
value of RPE on the display.
• The insulation test voltage is shown momentarily
next to the Riso enunciator.
• The unit will proceed with the Insulation and
Leakage tests.
Note: The power switch on the appliance under
test must be in the ON position to perform
an insulation test. If no appliance is
detected the DLPT2+ will display the
following.
21

Operating Instructions
• Check that the appliance power switch is in the
ON position. The test will automatically proceed
if the appliance power switch is placed in the
ON position.
• If the LO LOAd enunciator remains on the
display, the load presented by the appliance
may be too small for the DLPT2+ to detect. In
this case, press the CLI test key to continue.
• If the Insulation Resistance is greater than the
factory set limit a tick is placed next to the Riso
enunciator. If the Insulation Resistance is less
than the set limit a cross is placed next to the
Riso enunciator, the FAIL enunciator is
displayed and the test sequence is halted.
Note: If a mains supply is detected, the DLPT2+
will perform a differential leakage test.
If the DLPT2+ does not detect a mains
supply then the DLPT2+ will perform a
substitute leakage test.
• If a substitute leakage test is performed then the
DLPT2+ will start the test without the need for
user intervention. If the substitute leakage is less
than the factory set limit a tick is placed next to
the Iea enunciator.

Leakage test by flashing the Ileak icon. If no key
is pressed the DLPT2+ will timeout and return to
the start screen.
Note: If the LKGE key is pressed momentarily the
differential test duration is 5s.
If the LKGE key is pressed and held for 2s
the differential test duration is 2 minutes.
When the duration is set to 2 minutes, the
test can be terminated at any time by
pressing the LKGE key.

4 Memory & Print Functions
The DLPT2+ can store the results for a maximum of
999 appliances.
4.1 Saving Test Results
In order to store a test result press the STORE Key
when the test sequence has been completed. The
results displayed on the LCD will be recorded in
memory. Once the results for a test sequence have
been recorded the STORE Key is disabled until
another test sequence has been performed.
4.2 Viewing Test Results
When the DLPT2+ is waiting to start a new test
sequence press the RECALL Key, this will display
the last recorded results. Other results can be
displayed by scrolling through the memory. To scroll
through the memory use the RECALL and STORE
Keys. Pressing any other Key or waiting for 10
seconds will return the DLPT2+ into test mode.
4.3 Deleting Test Results
To delete all of the results in memory press and hold
the STORE and RECALL keys together while
displaying the recalled results until the counter
reaches zero.
4.4 Transferring Test Results
Test data can be transferred to a PC using the
Datalogger on the provided DLPT2+ Support CD.
Insert the CD into your disc drive and then view the
InstallationInstructions.txt file for information on how
to install.
Once the USB drivers and Datalogger are installed
you can open the Datalogger program from your
desktop.
Connect your device to the PC using a USB
connector. (The very first time you do this, your PC
will automatically install a COM port driver). You can
check which COM port is being used by looking in
the Device manager.

Select the correct COM port.
Click on Download. A progress bar will appear.
On the DLPT2+ in order to transfer the entire test
storage area to PC press and hold the RECALL key
for 5 seconds. The data will be transmitted using the
USB interface.
When all data has been captured and stored the
progress bar will disappear and you will be asked
where to save the data.
Once the file is saved you may click the "Open"
button to open the document with default
application.
For example, if you saved the file in .csv format (the
default) then it may open using a spreadsheet
application.
4.5 Printing Test Results
In order to print a test label press the PRINT Key
when the test sequence has been completed or
when the test result is being reviewed. The printer
must be attached before the PRINT Key is pressed.
In order to save power the DLPT2+ will turn the
printer on and off when required.
4.6 Setting the Real Time Clock
Setting time and date:
Ensure that the DLPT2+ is powered off. Press and
hold the RECALL key and then press simultaneously
the class I and class II keys to power on the tester.
The date format and time format is shown as
follows:
MM.DD = month (1-12). Day (1-31)
YYYY = year
HH.mm = hours (0-23).minutes (0-59)
SS = seconds (0-59)
Press the class I key to select a date field and time
field.
A flashing digit shows that this field can be set.

6 Maintenance
Operating Instructions
Clean only with a dry cloth; do not use solvents.
Before use, ensure unit is clean and dry; visually
inspect all leads, connectors, and case. Any
damage or wear must be rectified to preserve user
safety.
Check the battery contacts and compartment are
free of electrolytic contamination.
Any contamination of the battery contacts or
compartment should be cleaned with a dry cloth.
Note: The DLPT2+ contains no user serviceable
parts. If an Error warning should appear on the
display please contact the manufacturer or an
authorised DILOG Service Agent for advise.
7 Battery Check
The DLPT2+ is powered from 6 AA cells which are
checked before a test is performed. When the
battery voltage is low the enunciator is
illuminated. The unit will continue to perform within
specification for a limited number of tests,
dependent upon the type of the batteries fitted.
When the battery voltage reaches a level where the
performance is affected the enunciator will
flash and all test keys are disabled. The batteries
must be replaced.

7.1 Battery Replacement
Before opening the DLPT2+ ensure that all
test leads are disconnected.
• Switch off the unit by pressing and holding
the CLI and CLII keys.
• Disconnect all leads from the DLPT2+.
• Place the DLPT2+ face down and release
the captive screw in the battery
compartment cover.
• Remove the battery compartment cover and
remove the discharged batteries.
• Insert the replacement batteries into the
battery compartment ensuring that the
battery polarity matches the marking on the
inside of the battery compartment.
• Relocate the battery cover over the battery
compartment and fasten in position with the
battery cover captive screw.

9 Service and Calibration
Operating Instructions
To maintain the specified accuracy of the
measurement results, the instrument must be
recalibrated at regular intervals by either the
manufacturer or an authorised service agent. We
recommend a recalibration period of one year.
