1 DESCRIPTION

The Models MR415 and MR416 are clamp-on current probes that measure DC
currents up to 600A, AC currents up to 400A
AC+DC currents without opening the circuit in which the currents flow. They
indicate the shape and amplitude of the current measured in the form of a
voltage.

These instruments can be used with a multimeter, wattmeter, recorder, and other
instruments. They can be powered by a battery or with 5V
micro‑USB cable.

The MR415 and MR416 include the following features:

 overage indicator

 power

 zero adjustment

 Auto Standby feature

 one or two ranges, depending on the model (sensitivity 1 and 10mV/A)

 micro‑USB connector to connect an external power supply

2 OPERATION

Before changing batteries: set the switch to OFF and remove the clamp

2.1 Battery Installation

from the circuit under measurement.

1. Using a screwdriver, remove the battery compartment cover (1) from the
back of the housing (see Figure 2).

2. Connect the battery to the snap-on connector (2), observing polarity.

3. Place the battery into the battery compartment (3).

4. Replace the battery compartment cover and screw it onto the housing.

Figure 2

2.2 External Power (Optional)

For long‑term measurements, you can connect the clamp to external power via
any micro‑USB adapter that delivers 100mA or more. If external power is
disconnected, the clamp automatically switches to battery operation.

The isolation between the type B micro‑USB connector and the measurement
output is 600V CAT III. This enables you to safely connect the clamp to
measuring instruments with uninsulated inputs. The type B micro‑USB connector
must not be in contact with conductors or uninsulated parts at dangerous voltage.

When operating on external power, the Auto Standby feature is disabled. The
color of the ON indicator shows whether automatic standby is enabled (green) or
disabled (yellow).

2.3 Turning ON the Instrument

DC Zero must be adjusted before each measurement.

Turn on the clamp by pushing the slide switch to the 1mV/A or 10mV/A setting:

 1mV/A corresponds to the 600A range (MR415 and MR416)

 10mV/A corresponds to the 60A range (MR416)

The green ON indicator should light up:

 If indicator blinks, less than 4 hours of battery life remains

 If indicator fails to light, replace the battery (see § 4.2)

2.4 Auto Standby

After 10 minutes of operation without user action (such as pressing the DC Zero
button), the clamp automatically enters Standby mode. In this mode, the ON
indicator goes OFF.

To reactivate the clamp, press DC Zero button or change the switch to any
setting other than OFF.

To disable automatic Standby, press and hold down DC Zero when turning the
instrument ON. The ON indicator blinks to indicate that the request has been
applied; and then glows steady yellow when you release the DC Zero button.

2.5 DC Zero Adjustment

1. Remove the clamp from the circuit under measurement.

2. Turn the clamp ON.

3. Connect the clamp to the measuring instrument. The phase is on the

red lead.

4. Press the DC Zero button.

5. The OL indicator lights for approximately three seconds to indicate that
the zero adjustment is in progress.

6. If the zero has been correctly adjusted, the OL indicator goes OFF.

If it remains ON, the zero cannot be adjusted. In this case, ensure the

clamp is not on a conductor and that its jaws are correctly closed. Then
press DC Zero again.

Alternately, turn the clamp OFF and then back ON. The previous zero
adjustment will remain in effect.

2.6 Measurements

2.6.1 Making a Measurement

After adjusting DC Zero:

1. Press the clamp trigger to open the jaws.

2. Clamp the jaws around the conductor to be measured. Use the
centering marks on the jaws to position the clamp around the conductor.
If the measurement is to be used in a power calculation, ensure the
arrow on the clamp jaws (see Figure 1) points in the direction of the
current flow: source

3. Release the trigger, ensuring the jaws are completely and correctly

closed.

4. Observe the measurement displayed on the measuring instrument.

5. If the OL indicator lights, the current is too high to be measured. If you

are using the MR416 and the sliding switch is set to the 10mV/A range,
change the setting to 1mV/A.

load.

Figure 3 (MR416 shown)

2.6.2 Converting to Current

The Models MR415 and MR416 can both measure current up to 600A, with 1mV
corresponding to 1A. In addition, the MR416 provides a second measurement
range up to 60A, with 10mV of output corresponding to 1A.

To convert the clamp output to current, divide the voltage reading on the
connected measuring by the V/A coefficient. For example, in the 60A range a
reading of 45mV corresponds to a current of 4.5A.

4 MAINTENANCE

Except for the battery, the instrument contains no parts that can be

replaced by personnel who have not been specially trained and
accredited. Any unauthorized repair or replacement of a part by an
"equivalent" may gravely impair safety.

4.1 Cleaning

 Disconnect the instrument completely.

 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 clamp jaws as clean as possible.

4.2 Battery Replacement

The battery must be replaced if the ON indicator remains unlit when the
instrument is turned ON.

1. Disconnect the instrument completely and set the switch to OFF.

2. Remove the battery compartment cover from the instrument casing (see §

2.1).

3. Remove the old battery.

4. Insert the replacement battery into the snap-in battery connector, and place
it into the battery compartment.

5. Replace the battery compartment cover.
