Introduction
The Fluke Models 1503, 1507, and 1508 are battery-powered insulation testers (hereafter,
Tester or UUT). 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. CAT IV Testers protect against transients from the
primary supply level (overhead or underground utility service).
Although this manual contains calibration information for Models 1503, 1507, and 1508,
all illustrations and examples assume use of Model 1507. Table 1 provides a description
of all the symbols used in this manual.
The information provided in this manual includes the following:
• Warnings and Safety Information
• Specifications
• Basic Maintenance
• Performance Test Procedures
• Calibration Adjustment Procedure
• Replaceable Parts and Accessories
The information provided in this manual should only be used by qualified personnel. For
complete operating instructions and additional safety information, refer to the 1507/1503

Safety Information
To avoid possible electric shock or personal injury, follow these
guidelines:
• Use the Tester only as specified in this manual or the protection
provided by the Tester might be impaired.
• Do not use the Tester or test leads if they appear damaged, or if the
Tester is not operating properly. If in doubt, have the Tester serviced.
• Always use the proper terminal, switch position, and range for
measurements before connecting Tester to circuit under test.
• Verify the Tester’s operation by measuring a known voltage.
• Do not apply more than the rated voltage as marked on the Tester,
between the terminals or between any terminal and earth ground.
• Use caution with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc.
These voltages pose a shock hazard.
• Replace the battery as soon as the low battery indicator (b) appears.
• Disconnect circuit power and discharge all high-voltage capacitors
before testing resistance, continuity, diodes, or capacitance.
• Do not use the Tester around explosive gas or vapor.
• When using the test leads, keep your fingers behind the finger guards.
• 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.

Basic Maintenance
This basic maintenance section of the manual contains tests and procedures that require
no equipment other than the Tester and some consumables such as fuses and batteries.
Also, internal access is limited to the battery and fuse compartment.
Cleaning
When cleaning is necessary, wipe the Tester with a damp cloth and mild detergent. Do
not use abrasives or solvents. Dirt or moisture on the terminals can affect readings.
Testing the Batteries
XWWarning
To avoid electrical shock or personal injury, replace the
batteries as soon as the battery indicator (B) appears. A weak
battery can cause false readings.
The Tester continuously monitors battery voltage. If the low battery icon (B) appears
on the display, there is minimal battery life left. Before any performance test, check the

The Tester keys behave as follows when you perform the calibration adjustment
procedure:
T stores the calibration value and advances to the next step.
H ignores the calibration value and advances to the next step. This key is also
used to exit the calibration function after the calibration adjustment sequence
is complete.
Use the following steps to make calibration adjustments to the Tester. If the Tester is
turned off before completion of the adjustment procedure, the calibration constants are
not changed.
1. Remove batteries from UUT battery compartment. Connect a + 5.0 V lab supply
to the + and − battery terminals.
2. While holding down L, turn the rotary function switch from OFF to VAC.
The Tester displays CAL.
3. Press the blue button once to see the calibration counter.
4. Press blue button again to start the password entry. ---- appears on the display.
5. Press four keys to enter the password.
6. Press the blue button to go to the first calibration step. The Tester displays C-01 if
the password is correct. If the password is not correct, the Tester emits a double
beep, displays ---- and the password must be entered again. Repeat step 4.
7. Using Table 10, apply the input value listed for each calibration adjustment step.
For each step, position the rotary function switch and apply the input to the
terminals as indicated in Table 10.
8. After each input value is applied, press T to accept the value and proceed to
the next step (C-02 and so forth).
Note
After pressing T, wait until the step number advances before changing
the calibrator source or turning the Tester rotary function switch. If the
Tester rotary function switch is not in the correct position, or if the
measured value is not within the anticipated range of the input value, the
Tester emits a double beep and will not continue to the next step. Some
adjustment steps take longer to execute than others (10 to 15 seconds). For
these steps, the Tester will beep when the step is complete. Not all steps
have this feature.
9. After the final step, the display shows End to indicate that the calibration
adjustment is complete. Press C to go to meter mode.

Note
Set the calibrator to standby prior to changing the function switch position
and or after completing adjustment of each function. If the calibration
adjustment procedure is not completed correctly, the Tester will not operate
correctly.
