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.

AC/DC 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%.

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”.
