KLEIN TOOLS ET600 overview

A step-by-step process in guiding a customer through testing our DITRA-HEAT-E-HK heating cables. This unit is capable of performing all required and optional testing. When testing the cable, ensure customer has breaker TURNED OFF

TESTING GUIDE

TEST 1Conductor resistance

TIPS

STEPS

1. Turn multi-meter to the continuity setting
2. Connect the probes to the exposed heating cable conductors
3. Compare the measured resistance with the factory value printed on the factory tag
4. Ensure measurement is within 10% of the factory value. If it varies more than 10%, the cable may be damaged

• No polarity exists during testing; meaning you can connnect red to red or red to black, it does not make a difference
• If not using alligator clips, ensure customer is not making skin contact with exposed cable as it can cause inaccurate readings
• The cable does not always need to be removed from terminal for testing, but this may lead to inaccurate results. It is usually best to have them remove the cable

TEST 2Conductor & ground braid continuity

TIPS

STEPS

• If any numerical value is shown during test 2, it usually indicates a failed cable
• This test is to show a complete loop between cable and ground with no breaks, hence why OL is a passing test

1. Turn multi-meter to the continuity setting, the same as test 1
2. Connect one probe to either the white/yellow/red or black heating cable lead
3. Connect the other probe to the exposed ground braid (silver or copper cable)
4. A successful test will produce a value of OL (overload) which indicates there is no current shorting from conductor to ground
5. Repeat process for the other color cable lead

TEST 3INSULATION RESISTANCE TEST

TIPS

STEPS

1. Turn multi-meter to 1kV
2. Connect one probe to either the white/yellow/red or black heating cable lead
3. Connect other probe to the exposed ground braid (silver or copper cable)
4. Press and hold the blue 'TEST' button
5. A passing cable will read 4,000v
6. Repeat process for the other color cable lead

• The insulation resistance test is optional and is not required for warranty purposes. The benefit of performing this test extends the warranty to 15 years
• Note that the number displayed under the reading is the amount of volts currently being applied to the cable. That number is not indicative of a passing or failing cable. The number will constantly decrease until it reaches 0
• A failing test will be a reading of anything under 1,000 volts. This means the cable is not receiving back the amount of volts it initially sent

TEST 4FLOOR TEMPERATURE SENSOR TEST

TIPS

STEPS

1. Turn multi-meter to the ohms setting
2. Insert the probes directly into the 3rd and 4th screw terminals on the front of the thermostat. This is where the sensors are installed.
3. The reading will differ depending on temperature of the room, but should be between 8-20
4. Repeat process for back-up sensor (if applicable)

• The sensors do not need to be removed from the screw terminals to test
• Back-up sensor may be located behind the thermostat near the heating cable
• If two sensors are simultaneously installed in the 3rd and 4th ports (a common occurance), you will most likely get a failed reading
• If back-up sensor is not stripped, testing is not necessary

The settings we will use during testing

• o))) - Cotinuity - Used for conductor resistance test (test 1) and conductor and ground braid continuity test (test 2)

• 1kV - 1000 volts - Used for insulation resistance test (test 3)

• Ω - K-ohms - Used for floor temperature sensor test (test 4)

CABLE PORTS

Customer will plug testing cables into these ports

• COM - Black cable

• +VΩ - Red cable

Note: Alligator clips are the recommended type of clips due to ease of use
