  • Seite 9 • Place test leads in proper input terminals. • Do not use the Meter with any parts or cover removed. • Use only Fluke approved replacement parts, and accessories as specified in this manual. • Do not use the Meter if the safety shutter is impaired in any way. The safety shutter (see Frontispiece) prevents access to the test terminals and charger terminals at the same time.

  • Seite 13 Use a qualified recycler or hazardous materials handler to dispose of dead batteries. Contact your authorized Fluke Service Center for disposal and recycling information. Storing rechargeable lead-acid batteries in a low-charged state could lead to reduced life and/or damage.
  • Seite 14 1550B Users Manual Using the Guard Terminal Note Insulation resistance is measured between the + and − output connections. The Guard terminal (G) is at the same potential as the negative (−) terminal but is not in the measurement path.
  • Seite 15 MegOhmMeter Operating the Meter Figure 6 shows how to prevent surface current leakage by connecting a lead from the Guard terminal to a conductor wrapped around 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.
  • Seite 16 Figure 8. Connecting to the Circuit Under Test Note The 1550B is NOT specified below 200 kΩ. This means shorting the leads and performing a test, results in an unspecified but above zero reading. This is normal for this meter’s input circuitry configuration and does not affect readings...
  • Seite 17 MegOhmMeter Making Measurements Options to Consider Before Making an Insulation Test In addition to performing a basic insulation test, the Meter includes a series of features/functions that allow you to more precisely tailor the test to your requirements. These include defining a test voltage, selecting a ramp test, setting a time limit (duration) for the test, measuring polarization index (PI), measuring dielectric absorption ratio (DAR), and measuring capacitance.
  • Seite 18 1550B Users Manual Programming a Test Voltage To set a test voltage in between the pre-set test voltages proceed as follows: button to select TEST VOLTAGE. With the Meter turned on, press the Test Voltage Display 500V ASW05F.EPS Press the button to scroll through the pre-set test voltage options (250 V, 500 V, 1000 V, 2500 V, and 5000 V).
  • Seite 19 MegOhmMeter Making Measurements Selecting 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.
  • Seite 20 1550B Users Manual Polarization Index (PI) As part of the insulation test, the Meter measures and stores polarization index (PI), when appropriate. Since, by definition, a polarization index test requires 10 minutes to complete, it is measured and stored as invalid data for all insulation tests under 10 minutes.
  • Seite 21 MegOhmMeter Making Measurements To perform an insulation test use the following procedure: With the Meter turned on, set the available measurement options to meet your test requirements. These include: • Test Voltage – Set range: 250V to 5000 V (50 V/100 V steps) •...
  • Seite 22 1550B Users Manual Following termination of an insulation test the Meter beeps when a potentially hazardous voltage remains on the test terminals due to charged-circuit capacitance or from the presence of an external voltage. When the test is terminated, STORE RESULT? is displayed. If appropriate, store the test results as described in the next procedure.

  • Seite 25 Before the USB-IR cable can be used, software drivers must be installed on your Windows PC. See the USB-IR Installation Guide for more information. To connect the 1550B to the PC for use with FlukeView Forms Basic Documenting Software: The 1550B should not be running a test; otherwise, serial communications will be disabled.
