Fluke does not warrant that software will be error free or operate without interruption.

Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke authorized sales outlet or Buyer has paid the applicable international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country is submitted for repair in another country.

Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective product which is returned to a Fluke authorized service center within the warranty period.

To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information, then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition of operation or handling, including overvoltage failures caused by use outside the product’s specified rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of repair costs and obtain authorization before commencing the work. Following repair, the product will be returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).

Introduction

To prevent electrical shock or personal injury, do not do the calibration verification tests or calibration procedures in this manual unless you are qualified.

The data in this manual is for qualified personnel only.

This manual tells you about verification and adjustment procedures for the 772/773 Milliamp Process Clamp Meter (referred to in this manual as the Meter). The Meter features closed-case calibration to use with reference sources. It measures the reference signals, calculates the correction factors, and keeps them in memory. Calibration adjustment is required after a repair, or if the Meter fails a performance test.

Safety Information

In this manual, a Warning identifies conditions and procedures that are hazardous to the user. A Caution identifies conditions and procedures that could cause Meter damage, equipment under test damage, or permanent loss of data.

To prevent electrical shock or personal injury, and to prevent damage to the Meter, follow these guidelines:

• Read this manual before use and follow all safety

instructions.

• Use the Meter only as this manual recommends. To use the

Meter incorrectly, compromises the safety features of the Meter.

• Examine the case before you use the Meter. Look for

cracks, missing plastic or missing pieces of the clamp and cable. Do not use if the clamp or Meter is damaged.

XWWarning

• Do not use on voltages >33 V ac rms, 47 V ac peak, or 70 V

dc.

• Do not use to measure ac current.

• Do not use to measure ac voltage.

• Do not work alone.

• Use maximum precautions when you work near bare

conductors or bus bars. If you touch the conductor, you can receive an electrical shock.

• To prevent incorrect indications that can cause electrical

shock and injury, replace the batteries when the lowbattery indicator (B) appears.

• Follow local and national safety codes. You must use

protective equipment to prevent an electrical shock and arc blast injury where hazardous live conductors are exposed.

Milliamp Process Clamp Meter

Safety Information

• When you measure, keep your fingers behind the Tactile

Barrier. See Figure 1.

• Do not use with a non-insulated conductor.

• Do not use near strong magnetic fields.

• Remove test leads before you open the case.

WCaution

To prevent damage to the Meter, do not open it. Do not use a solvent to clean the Meter, and do not put the Meter in water.

Basic Maintenance

How to Clean the Meter

Battery Replacement

XWWarning

To prevent electrical shock or personal injury, repairs or servicing not included in this manual must be done only by qualified personnel.

XWWarning

To prevent electrical shock or personal injury, remove test leads before you clean the Meter.

W Caution

To prevent damage to the Meter, do not use aromatic hydrocarbons or chlorinated solvents when you clean the Meter. These solutions react with the plastics used in the Meter.

Clean the instrument case with a damp cloth and mild detergent.

XWWarning

To prevent incorrect Meter indications that could cause possible electrical shock or personal injury, replace the batteries when the low battery indicator (B) appears.

To prevent electrical shock, remove test leads before changing the batteries.

To replace the batteries, see Figure 2:

1. Turn the Meter off.

2. Use a flat-head screwdriver to loosen the battery compartment door screws, and

remove the door from the case bottom.

3. Remove the batteries.

4. Replace the batteries with four new AA batteries.

5. Reattach the battery compartment door to the case bottom and tighten the screws.

static awareness

A Message From

Fluke Corporation

Some semiconductors and custom IC's can be damaged by electrostatic discharge during handling. This notice explains how you can minimize the chances of destroying such devices by:

1. Knowing that there is a problem.

2. Learning the guidelines for handling them.

3. Using the procedures, packaging, and bench techniques that are recommended.

The following practices should be followed to minimize damage to S.S. (static sensitive) devices.

1. MINIMIZE HANDLING

2. KEEP PARTS IN ORIGINAL CONTAINERS UNTIL READY FOR USE.

3. DISCHARGE PERSONAL STATIC BEFORE HANDLING DEVICES. USE A HIGH RESIS TANCE GROUNDING WRIST STRAP.

4. HANDLE S.S. DEVICES BY THE BODY.

5. USE STATIC SHIELDING CONTAINERS FOR HANDLING AND TRANSPORT.

6. DO NOT SLIDE S.S. DEVICES OVER ANY SURFACE.

8. WHEN REMOVING PLUG-IN ASSEMBLIES HANDLE ONLY BY NON-CONDUCTIVE EDGES AND NEVER TOUCH OPEN EDGE CONNECTOR EXCEPT AT STATIC-FREE WORK STATION. PLACING SHORTING STRIPS ON EDGE CONNECTOR HELPS PROTECT INSTALLED S.S. DEVICES.

9. HANDLE S.S. DEVICES ONLY AT A STATIC-FREE WORK STATION.

7. AVOID PLASTIC,VINYL AND STYROFOAM IN WORK AREA.

Display Hold Test

Changes to the input signal will not register on the Meter display when in Display Hold Mode. To prevent electrical shock or personal injury, you must be aware of what mode the Meter is in.

Push H to activate Display Hold mode. The display shows I and the display freezes. Push H a second time to exit and resume normal operation.

Backlight Test

Push Q to turn the backlight on and off. To extend battery life, the backlight automatically stops after 2 minutes.
