Insulation Tester Safety Information Safety Information Warning: Read before Tester use. To prevent possible electrical shock or personal injury, follow these guidelines: • Before and after testing, confirm that the Tester does not indicate the presence of a hazardous voltage, see Figure 3. If the Tester beeps continuously and a hazardous voltage is shown on the display, remove power from the circuit under test or allow the installation capacitance to fully discharge.
1550C/1555 Users Manual • • • • • • • • • • 4 Do not exceed the voltage or measurement category (CAT) rating of the test probes/accessories. Not all accessories provided are for use at the full-rated output voltage of the Tester. Accessories rated to 1000V CAT III/ 600V CAT IV are intended for hands-free use during insulation testing and are not to be touched while the output of the Tester exceeds the accessory’s marked rating.

Insulation Tester The Tester Charge the Battery Pb = Note This Tester uses a rechargeable 12 V lead-acid battery for power. Do not mix with the solid waste stream. Use a qualified recycler or hazardous materials handler to discard dead batteries. Contact your approved Fluke Service Center for disposal and recycling data. Storing rechargeable lead-acid batteries in a low-charged state could decrease their life and/or damage them.
1550C/1555 Users Manual To charge the battery with the ac power supply: 1. Turn the Tester off. 2. Disconnect the test leads from the Tester. 3. Move the safety shutter to access the power supply connection. 4. Connect the ac power cord to the IEC ac power socket on the Tester. 5. Connect the other end of the power cord to an ac power supply. See “General Specifications” for ac charger input specifications. The LCD displays CHARGING. Downloading is possible when the Tester is in Charging mode.
Insulation Tester The Tester Shield ( ) ( ) Surface Leakage Current GHH13.EPS Figure 6. Surface Leakage Current Figure 7 shows how to prevent surface current leakage with a lead connected from the Guard terminal to a conductor that surrounds the inner insulation. The surface leakage current is directed to the Guard terminal. This removes the leakage current from the measurement path between the positive and negative terminals, and improves the accuracy of the test readings.

Test Lead Connections Note The Tester is NOT specified below 200 kΩ.
1550C/1555 Users Manual Before an Insulation Test The Tester includes features and functions that let you adapt the test to your requirements. These features let you: • define a test voltage • make a ramp test selection • set a time limit (duration) for the test • measure polarization index (PI) • measure dielectric absorption ratio (DAR) • measure capacitance Use these alone or in combination. Set, clear, or account for (as appropriate) each feature before you start an insulation test.
Insulation Tester Measurements Note The actual test voltage can be up to 10 % higher than the selected test voltage. Program a Test Voltage To set a test voltage in between the preset test voltages, proceed as follows: 1. With the Tester turned on, push to select TEST VOLTAGE. Test Voltage Display GHH05.EPS 2. Push or to scroll through the preset test voltage options (250 V, 500 V, 1000 V, 2500 V, 5000 V, and 10,000 V). Select the voltage closest to the level required. 3.
1550C/1555 Users Manual Select a Ramp or Steady-State Test The ramp-test function is an automated test that checks insulation for a breakdown. During a ramp test, the output voltage starts at 0 V and increases linearly (100 V/s) until it reaches the specified test voltage or until a sudden drop in measured resistance is detected. Then, the Ramp stops, the test voltage drops to zero, and the voltage at the breakdown point is stored in memory on the Tester.
Insulation Tester Measurements 3. Push to call the menu item. 4. Push or to select the time. 5. Push or to use the settings. starts the test. Polarization Index (PI) As part of the insulation test, the Tester measures and stores polarization index (PI), when appropriate. A polarization index test requires 10 minutes to complete. Therefore, the Tester will start a countdown at 10 minutes. When an insulation test is 10 minutes or more, the polarization test is completed and stored.
1550C/1555 Users Manual Insulation Test XW Warning To avoid possible electric shock or personal injury: • Be aware that measuring insulation resistance requires the application of potentially dangerous voltages to the circuit. This may include exposed bonded metalwork. • Remove all power from the circuit under test and discharge circuit capacitance before testing a circuit with the Tester. • Before proceeding, ensure that the installation is wired correctly and no personnel are endangered by any tests.
Insulation Tester Measurements XW Warning Before and after testing, confirm that the Tester does not indicate the presence of a hazardous voltage, see Figure 4. If the Tester beeps continuously and a hazardous voltage is shown on the display, disconnect test leads and remove power from the circuit under test. 3. Push for 1 second to start the insulation test.
1550C/1555 Users Manual If breakdown occurs with ramp test enabled, push before going to step 4. Following termination of an insulation test, the Tester beeps when a potentially hazardous voltage remains on the test terminals due to charged-circuit capacitance or from the presence of an external voltage. 4. When the test is terminated, STORE RESULT? Is displayed. If appropriate, store the test results as described in the next procedure. Otherwise, terminate the STORE RESULT? Prompt by pushing .
