i410/i1010
AC/DC Current Clamp
Service Information
WWarning
To avoid electric shock:
• Do not service this Current Clamp unless you are qualified to do so.
The service information provided in this document is for use by quali-
fied personnel only.
• Always remove input signals from the Current Clamp before opening
the case.
• Be careful when working with voltages that exceed 30V ac rms, 42.4V
pk, or 60V dc.
• The Current Clamp is protected throughout by double insulation. When
servicing the Current Clamp, use only specified replacement parts.
Caution
• If the Current Clamp is to be Calibrated, you must have a replacement
decal. See the Replacement Parts section for further details.
• This Current Clamp contains parts that can be damaged by static dis-
charge. Follow the standard practices for handling static sensitive de-
vices.
Introduction
Service Information covers the following service-related areas for the i410/i1010 AC/DC Current
Clamps:
• Product specifications
• Required equipment
• Performance test procedure and test values
• Preparing for calibration
• Calibration procedure
• Reassembly procedure
• Replacement parts
Usually, service information in this document applies to both models (i410 and i1010). Information ap-
plicable to only one model is so noted. For operating information, refer to the Instruction Sheet that came
with the Current Clamp.

Service Under Warranty
The Current Clamp is warranted to be free from defects in material and workmanship for one year.
The warranty does not cover abuse, batteries, or damage caused by using the Current Clamp outside its
rated specifications or operating environment. The complete warranty statement appears in the Current
Clamp Instruction Sheet.
For repairs:
• In the USA or Canada, call 1-800-323-5700
• Outside the USA, contact your nearest Fluke Distributor or Service Center.
Service, repairs, and replacement parts are warranted for 90 days.
Specications
General specifications are shown in Table 1. Range and accuracy specifications are shown in Table 2.
The accuracy of the Current Clamp is specified for one year after calibration, at 18°C to 28°C (64°F to
82°F), with relative humidity to 90%.

Required Equipment
Equipment required for the performance test and calibration procedure is shown in Table 3.
Table 3. Required Equipment
Equipment Recommended Model
Calibrator Fluke 5700A, 5720A, or 5500A
Transconductance Amplifier Fluke 5220A
Digital Multimeter (DMM) Fluke 45 or equivalent
Current Coil Fluke 5500A/Coil (50-Turn)
Calibration tool (slotted, as required)
Decal (replace to calibrate) PN 642584 (i410) or 642592 (i1010)
Performance Test
WWarning
To avoid electric shock, do not execute the performance tests unless the
Current Clamp is fully assembled.
The Battery LED and Measurement Accuracy tests verify that the Current Clamp is working properly
and performs to specification.
Battery LED Test
Complete the following procedure to verify that the Battery LED threshold is set correctly:
1. Turn on the Calibrator and allow it to warm up and stabilize for 30 minutes.
2. Place the Current Clamp face down.
3. Remove the screw securing the battery cover to the back of the Current Clamp.
4. Remove the battery cover.
5. Connect the Calibrator to the Current Clamp battery snap connectors.
6. Set the Calibrator to 6.70V dc. Check that the Current Clamp LED is off.
7. Set the Calibrator to 7.30V dc. Check that the LED is on.
8. Replace the battery cover and securing screw.
Measurement Accuracy Tests
Connect the Current Clamp and test equipment as shown in Figure 1. Then perform the appropriate steps
shown in Table 4. Most tests apply to both the i410 and the i1010, with resulting DMM readings listed
separately for each model. Some tests apply to only one model; the model not being tested is then
marked with “NA”.
