MAINTENANCE
Disconnect everything connected to the device and set the switch to OFF.
Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry rapidly
with a dry cloth or forced air. Do not use alcohol, solvents, or hydrocarbons.
Keep the air gap of the clamp perfectly clean.
REPLACEMENT OF THE BATTERIES
If the low battery symbol on the screen blinks, the batteries must be replaced promptly. Display
of the Lo bat message indicates that the batteries must be replaced for it to be possible once
again to use all functions of the clamp.
PROCEDURE
■ Disconnect everything connected to the device and set the switch to OFF.
■ Use a cross-headed or plain screwdriver to unscrew the 2 attachment screws and remove
the battery compartment cover.
■ Remove the old batteries and replace them with 4 new batteries having identical
characteristics (LR6, AA, 1.5V); observe the polarities.
Note: the alkaline batteries can be replaced by Cd-Ni or Ni-Mh rechargeable batteries (AA,
1.2V) having similar characteristics. However, the time between the low battery message
and the automatic switching off of the device will be shorter with the rechargeable batteries.
Spent batteries must not be treated as ordinary household waste.
Take them to the appropriate recycling collection point.
■ Close the battery compartment cover and screw the two screws back in.
■ Check the proper operation of the device.
PRESERVATION OF STORED DATA
When the batteries are removed, the data (recorded measurement values, alarm thresholds)
are preserved. The date and time must be reset if the batteries are out for more than 2
minutes.

ACCURACY CHECK
AEMC recommends to calibrate the meters once a year and to check the probe with the supply
5Ω loop.
EQUIPMENT
 1 high accuracy decade box: IET lab or equivalent,
 1 lead with known resistance
 1 AC current calibrator 50/60 Hz Fluke 5502 or equivalent
PROCEDURE
Place the lead in the jaws of the clamp and set the function switch of the device to Ω+A.
Connect the lead to the AC calibrator and supply the values from the table below.
Connect the lead to the decade box and set the dial to the table below. (be sure to include the
lead resistance)

MANUAL CALIBRATION PROCEDURES
The calibration procedure will not delete the factory defaults and it is possible to reset it
anytime from the SET-UP position.
Notes:
 Restoring Default Factory Calibrations will erase any previously performed user
resistance or current calibrations.
1.1 Setup and Activate Calibration Mode
1.1.1 Power on the ground tester and select “SET-UP” rotary switch position.
1.1.2 Select the “CAL.” menu by pressing the ▲ key one time.
1.1.3 Activate the “CAL.” menu by simultaneously pressing the ▲, ▼, and ► keys.
1.2 Restore Default Factory Calibration
1.2.1 Navigate to the “CAL. dFLt.” menu.
1.2.2 Press and hold the ► key until the “PrES. rt.” message appears and starts
blinking (press should last approximately 3 seconds).
1.2.3 Press the ► key. “End dFLt. PASS” will be displayed.
1.2.4 Press the ► key to return to the “CAL. dFLt.” menu.
1.3 User Resistance Calibration
1.3.1 Remove any conductors from the jaws of the ground clamp.
1.3.2 Navigate to the “CAL. R” menu.
1.3.3 Press and hold the ► key until the “PrES. rt.” and “no LOOP.” messages
appear and start alternately blinking (press should last approximately 3
seconds).
1.3.4 Press the ► key to start the open loop section of the calibration (“run CAL.R”
will be displayed for approximately 15 seconds).
1.3.5 When the “SEt 5.00Ω” message appears, insert a loop of known resistance
between 5 and 25Ω.

MODEL 6416/6417 SERVICE/CALIBRATION MANUAL CAT# 2141.01/2141.02
v1 – 11/23/15 - 12 -
1.3.6 Enter the resistance of the loop using the ▲ and ▼ keys and press the ► key
to start the next section of the calibration (“run CAL.R” will be displayed for
approximately 10 seconds).
1.3.7 “End CAL.R PASS” or “End CAL.R FAIL” will be displayed at the end of the
calibration. Press the ► key to save the new user calibration and return to the
“CAL.R” menu
1.3.8 Retry the calibration if failed.

carrying conductor.
1.3.13 Enter the current value using the ▲ and ▼ keys and press the ► key to start
the low current section of the calibration (“run CAL.I” will be displayed for
approximately 10 seconds).
1.3.14 When the “PrES. rt.” and “10.00 A SEt” messages appear and start
alternately blinking, run a known current between 9 and 10.5 A (60 Hz)
through the current carrying conductor.
1.3.15 Enter the current value using the ▲ and ▼ keys and press the ► key to start
the high current section of the calibration (“run CAL.I” will be displayed for
approximately 10 seconds).
1.3.16 “End CAL.I PASS” or “End CAL.I FAIL” will be displayed at the end of the
