PRECAUTIONS FOR USE

These instructions are intended to ensure the safety of users and proper operation

of the instrument. Failure to observe these safety instructions may result in electric

shock, fire, explosion, and destruction of the instrument and/or installations.

The operator and/or the responsible authority must carefully read and clearly

understand the various precautions to be taken in use.

Do not use the instrument on networks on which the voltage or category

exceeds instrument specifications.

Never exceed the protection limits stated in the specifications.

Observe the environmental conditions of use, including relative humidity,

altitude, degree of pollution, and place of use.

Do not use the instrument if it appears to be damaged, incomplete, or not

properly closed.

Before each use, check the condition of the insulation on the leads, housing,

and accessories. Any component on which the insulation is deteriorated (even

partially) must be set aside for repair or scrapping.

When handling the instrument, keep your fingers behind the physical guards.

Use suitable means of protection.

All troubleshooting and metrological checks must be performed by competent

and accredited personnel.

1 DESCRIPTION

The Models MR417 and MR527 are clamp-on current probes that measure DC

currents up to 1400A, AC currents up to 1000ARMS (1400A peak), and combined

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 oscilloscopes. They can be powered by a

battery or with 5VDC via the optional micro‑USB cable.

The MR417 and MR527 include the following features:

overage indicator

power supply indicator

zero adjustment

Auto Standby feature

two ranges (sensitivity 1 and 10mV/A)

micro‑USB connector to connect an external power supply

2 OPERATION

2.1 Battery Installation

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

from the circuit under measurement.

1. Using a screwdriver, remove the battery compartment cover (1) from the

back of the housing (see Figure 3).

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 3

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 insulation 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).
