GENERAL SAFETY PRECAUTIONS
This equipment can produce POTENTIALLY LETHAL VOLTAGES!
Improper operation or test practices may result in injury or death to the
operator or surrounding personnel.
The operation of High Voltage test equipment should only be performed by
personnel familiar with HIGH VOLTAGE testing and safety procedures. The
operator of this equipment must be aware of all hazards associated with High
Voltage testing. The operator is responsible for himself and others in close
proximity of the testing area.
Some General Safety Practices for working with High Voltage Test Equipment
have been listed below for your reference.
•Become familiar with your instrument before performing an actual test
•Know your work area, check that all circuits are de-energized and locked
out.
•Never work alone; always work with another qualified worker.
•Mark off entire work area with barriers and warning tape.
•Make all personnel aware of your testing activities.
•Be aware of dangerous conditions that may arise from energizing a test
specimen.
•Never modify test equipment, modifications to equipment could introduce
an unknown hazard or hinder a designed-in safety feature.
•DO NOT operate damaged equipment. Remove power, and do not use
the equipment until safe operation can be verified by service-trained
personnel.
Phenix Technologies, Inc. assumes no liability for unsafe or improper use of test equipment.

SECTION 1: DESCRIPTION
The Liquid Dielectric Test Set, Model LD60A, is designed to test and measure the dielectric
breakdown of insulating oil used in transformers, capacitors, bushings, etc. in accordance to
ASTM D877 and ASTM D1816. The standard test set also satisfies the requirements of IEC,
VDE, and BS standards.
The test set is a portable type built into a rugged carrying case. The Control Panel is below the
cover with the voltmeter and the high voltage test compartment. The test compartment is
provided with a see-through lid interlocked to the test circuit with a limit switch to ensure full
safety during operation.
As options, the test set can be supplied with two different kinds of test cells, either TC/VDE test
cell with VDE electrodes according to ASTM D1816, or TC/DE test cell with 1-inch flat electrodes
according to ASTM D877. Other cells are available upon request.
SAFETY FEATURES
•Center tapped high voltage transformer.
•The test cell is isolated from the supply when the protective lid is raised.
•Fast acting relay in series with the high voltage winding and the test cell ensures immediate
cutout at flashover above specified current levels.
•Control lamp indicating AC power on.
•Control lamp indicating failure.
•Fast acting fuses are located both in the input to the test set and in the primary of the high
voltage transformer.
OTHER FEATURES
•Input switch, fuse, and power indicator lamp.
•Motorized output voltage control from 0 to 60,000 volts with three selectable speeds of 500,
2000 and 3000 volts per second.
•Single range memory voltmeter connected across transformer primary calibrated to output
voltage level records breakdown voltage for the test sample.
•The test compartment is provided with a 115-volt outlet for convenient plug-in of motor driven
stirrer when testing to ASTM D1816 standards.

OPERATING INSTRUCTIONS
Operation
The test set is fully automatic. To gain test data, follow these procedures:
1. Place the prepared test cell in the test compartment;
2. Set voltage rate of rise switch to correct position;
3. Close test chamber lid;
4. Switch to start position.
It will automatically raise the voltage to the breakdown level, indicate “failure,” and the breakdown
level can be read on the voltmeter.
The Android tablet (Option) provides a convenient remote mode control option using Bluetooth
technology.

OPERATING INSTRUCTIONS
LD60A Android App (Remote Mode) (OPTION)
The LD60A may be ordered with an optional android tablet that is pre-loaded with the android
app. The app communicates with the LD60A via a Bluetooth link.
To use the app, the LD60A must be put in Remote Mode. With the LD60A powered on, push the
Remote Mode switch to ON. Launch the LD60A app, then press “Connect.” The Bluetooth link
will automatically shut down after 5 minutes of inactivity. When this happens, simply turn the
Remote Mode OFF then back ON again.
The app has two modes: “Automatic Test” and “Manual Controls.” Use “Automatic Test” to
perform a complete automatic test per the desired test standard. Use “Manual Controls” to
perform a single simple test.
To perform an Automatic test, first select the desired test standard to follow. Then optionally, you
may enter these values: Test ID, Oil Test Temp, Oil Sample Temp, and Oil Type. These values
represent the measured temperature of the oil. You may also change the gap and indicate
whether you used a stirrer. Press “Start Test” to initiate a test. The results will be collected and
displayed. When the test is complete, press “Test Report” to see the results. This report may
then be sent to a printer or shared via email.
Pairing with the LD60A
If for some reason you need to re-establish the paring with the LD60A, follow the instructions in
this section. Pairing creates a bond between a Bluetooth device and a host device. A host
device is an Android device (tablet, phone, or mini-PC).
The LD60A must be paired with the host device before it can establish a wireless connection and
transmit acquired data to the device. The LD60A only has to be paired once with a particular host
device.
To pair the LD60A:
1. Make sure the host device is configured to host a Bluetooth device. Refer to host device
documentation to learn how to enable Bluetooth and how to search for and pair with Bluetooth
devices.
2. Press and hold the Remote Mode On button AND the Device Pair button for at least five
seconds to put the device into pairing mode. When the BT Power and Pair LEDs blink
alternately, the device is in pairing mode and is ready to pair with the host device.
3. Select the Bluetooth device setup in the host device OS software, and then select the BTH-
1208LS-OEM when it displays. Refer to the Bluetooth documentation of your host device to
learn how to pair it with a Bluetooth device.
4. If host device requests a passkey, PIN or pairing code, enter the default value for the device
(0000).
5. Press and hold the BT Power button for two seconds to remove the device from pairing mode.

6. Move the start switch to start position when stand time requirements have been met.
7. High voltage will come on; the unit will automatically raise the voltage to the desired rate
per second until failure occurs.
8. If a failure occurs, the voltage will shut off, the failure light will illuminate, and the break-
down voltage will be indicated on the kilovolt meter.
9. To return to zero, switch the stop-reset switch to stop/reset.
10. Continue test as per ASTM D877.
11. Remove the test sample of oil and repeat the above procedure for other samples.
NOTICE: The voltmeter may continue to rise slightly after the failure indicator is tripped.
This meter response delay should be ignored. The final voltage reading is the
breakdown point.

SECTION 7: MAINTENANCE AND TROUBLESHOOTING
Maintenance
No maintenance is required besides the control of fuses and control lamps located on the front
panel. Ratings of these are described in the parts list.
No solution or chemical stronger than ordinary mild soap and water solution should be applied to
the cabinet area of this unit. Care must be used when cleaning the meter faces and console
panel. Abrasives may remove printing and descriptive titles and scratch meter faces. When
cleaning, always disconnect unit from power source.
CAUTION: Never attempt to clean inside the unit as the cleaning solution may cause damage to
the electronic components.
In the event it becomes necessary to replace any parts, a description can be found with the
supplied parts list.
Troubleshooting
No “power on.”
•Is the power cord plugged in?
•Is voltage available in the wall outlet?
•Check fuse F101.
•Check the control lamp for “Input power.”
The test procedure does not start.
•Is “Input power” turned on?
•Is the compartment lid closed? Check that the micro switch is clicking when closing the lid.
•Have you turned the toggle switch to start position?
•Have you reset the test set before start-up?
The voltmeter does not show any reading.
•Check test procedure start as above.
•Check fuse F2.
