1507/1503 Insulation Testers Introduction The Fluke model 1507 and model 1503 are battery-powered insulation testers (hereafter, "the Tester"). Although this manual describes the operation of both Models 1507 and 1503, all illustrations and examples assume use of model 1507. These Testers meet CAT IV IEC 61010 standards. The IEC 61010 standard defines four measurement categories (CAT I to IV) based on the magnitude of danger from transient impulses.
1507/1503 Users Manual Safety Information Use the Tester only as specified in this manual. Otherwise, the protection provided by the Tester may be impaired. See Table 1 for a list of symbols used on the Tester and in this manual. A XWWarning identifies hazardous conditions and actions that could cause bodily harm or death. A XWCaution identifies conditions and actions that could damage the Tester, the equipment under test, or cause permanent loss of data.
Insulation Testers Safety Information • • • • • • Remove test leads from the Tester before opening the Tester case or battery door. Never operate the Tester with the cover removed or the battery door open. Comply with local and national safety requirements when working in hazardous locations. Use proper protective equipment, as required by local or national authorities when working in hazardous areas. Avoid working alone. Use only the replacement fuse specified or the protection may be impaired.
1507/1503 Users Manual Unsafe Voltage Rotary Switch Positions To alert you to the presence of a potentially hazardous voltage, when the Tester detects a voltage ≥ 30 V in insulation test, ≥ 2 V in resistance, or a voltage overload (OL), the Z symbol is displayed. Turn the Tester on by selecting any measurement function. The Tester presents a standard display for that function (range, measurement units, modifiers, etc.).

The Tester displays CAL and enters Calibration mode when the button is released. Note Power Up options are active when the button is pressed. 10 Making Measurements The figures on the following pages show how to make measurements.
Insulation Testers Making Measurements Measuring Volts 1507 Measuring Earth-Bond Resistance Resistance tests should only be performed on de-energized circuits. Check the fuse before testing. See Testing the Fuse later in this manual. Connecting to an energized circuit while the test is active will blow the fuse. INSULATION TESTER Note Measurements can be adversely affected by impedances of additional operating circuits connected in parallel or by transient currents. To measure resistance: 1.
1507/1503 Users Manual • The primary display shows ---- until you press the T button and a valid resistance reading is obtained. 1507 5. • The high voltage symbol (Y) along with a primary display of >2 V warns if voltage greater than 2 V ac or dc is present. In this condition, the test is inhibited. Disconnect the Tester and remove power before proceeding. • If the Tester chirps when you press the T button, the test is inhibited because voltage is present at the probes.
Insulation Testers Making Measurements Measuring Insulation Resistance 4. Insulation tests should only be performed on de-energized circuits. To measure insulation resistance set up the Tester as shown in Figure 7 and follow the steps below: 1. Insert test probes in the V and COM input terminals. 2. Turn the rotary switch to the desired test voltage. 3. Connect the probes to the circuit to be measured. The Tester automatically detects if the circuit is energized.
1507/1503 Users Manual 1507 Measuring Polarization Index and Dielectric Absorption Ratios (Model 1507) INSULATION TESTER Polarization Index (PI) is the ratio of the 10-minute insulation resistance to the 1 minute insulation resistance. Dielectric Absorption Ratio (DAR) is the ratio of the 1-minute insulation resistance to the 30 second insulation resistance. Insulation tests should only be performed on de-energized circuits. To measure the polarization index or dielectric absorption ratio: 1.
Insulation Testers Measuring Polarization Index and Dielectric Absorption Ratios (Model 1507) 5. • The primary display shows ---- until you press the T button and a valid resistance reading is obtained. • The high voltage symbol (Z) along with a primary display of >30 V warns if voltage greater that 30 V ac or dc is present. If high voltage is present, the test is inhibited. • To interrupt a PI or DAR test before it is completed, momentarily press T.
1507/1503 Users Manual Using the Compare Function (Model 1507) Use the Compare function to set a pass/fail compare level for the insulation measurements. To use the Compare function: or bbw10f.eps Figure 8. Measuring Polarization Index and Dielectric Absorption Ratios 16 1. Press the C button to select the desired compare value. You can choose from 100 kΩ, 200 kΩ, 500 kΩ, 1 MΩ, 2 MΩ, 5 MΩ, 10 MΩ, 20 MΩ, 50 MΩ, 100 MΩ, 200 MΩ, and 500 MΩ. 2.
Insulation Testers Cleaning Cleaning 1507 Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings. Allow time for drying before using the Tester. INSULATION TESTER Testing the Batteries The Tester continuously monitors battery voltage. If the low battery icon (B) appears on the display, there is minimal battery life left. To test the batteries: 1.
1507/1503 Users Manual Testing the Fuse XWWarning To avoid electrical shock or injury, remove the test leads and any input signals before replacing the fuse. 315 mA 1507 INSULATION TESTER Fuse OK Test the fuse as described below and shown in Figure 10. Replace the fuse as shown in Figure 11. 1. Turn the rotary switch to the O position. 2. Press and hold T. If the display reading is FUSE, the fuse is bad and should be replaced. bbw06f.eps Figure 10.
Insulation Testers Replacing the Batteries and Fuse Replacing the Batteries and Fuse Replace the fuse and batteries as shown in Figure 11. Follow the steps below to replace the batteries. XWWarning To avoid shock, injury, or damage to the Tester: • To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the battery indicator (B) appears. • Use ONLY fuses with the amperage, interrupt, voltage, and speed ratings specified. • 1.
