Fluke warrants that software will operate substantially in accordance with its functional specifications for 90
days and that it has been properly recorded on non-defective media. 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

Introduction
XW Warning
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.
This manual explains:
• Precautions and Safety Information
• Specifications
• Basic Maintenance
• Calibration/Verification Procedure
• Replaceable Parts and Accessories
For complete use instructions, refer to the 772/773 Instruction Sheet.

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.
XWWarning
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.
• 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 low-
battery 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.

• 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
XWWarning
To prevent electrical shock or personal injury, repairs or
servicing not included in this manual must be done only by
qualified personnel.
How to Clean the Meter
XWWarning
To prevent electrical shock or personal injury, remove test
leads before you clean the Meter.

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.

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.

• Repairs or Meter servicing must be done only by qualified
personnel.
• Do not do the verification tests or calibration adjustment in
this manual unless qualified.
The tests that follow verify the functions of the Meter. If the Meter fails the verification
tests, repair is necessary. For Meter servicing, see “How to Contact Fluke”.
