PRECAUTIONS FOR USE

This device complies with safety standards IEC-61010-1 and 61010-2-032 for
voltages of 1000V in category IV at an altit ude OF les s t han 2000m , indoors, with a
degree of pollution not exceeding 2.
These safety instruct ions are intended to ensure the safety of persons and proper
operation of the device. If the tester is used other than as specified in this data
sheet, the protection provided by the device may be impaired.

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

understand the various precautions to be taken in use.

 If you use this instrument other than as specified, the protection it provides

may be compromised, thereby endangering you.

 Do not use the instrument in an explosive atmosphere or in the presenc e of

flammable gases or fumes.

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

exceeds those mentioned.

 Do not exceed the rat ed m axim um v olt ages and current s between terminals or

with respect to earth.

 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, hous ing,

and accessories. Any element of which the insulation is deteriorated (even
partially) must be set aside for repair or scrapped.

 Use leads and accessories rated for voltages and cat egories at least equal to

those of the instrument. If not, an accessory of a lower category lowers the
category of the combined Clamp + accessory to that of the accessory.

 Observe the environmental conditions of use.
 Do not modify the instrument and do not replace components with

"equivalents". Repairs and adjustments must be done by approved qualified
personnel.

 Replace the batt eries as soon as the

symbol appears on th e display unit.

Disconnect all cords before opening the battery compartment cover.

 Use personal protective equipment when conditions require.
 Keep your hands away from the unused terminals of the instrument.

6

English Clamp Multimeter METRA CLIP 87

 When handling the test probes, crocodile clips, and clamp ammeters, keep

your fingers behind the physical guard.

 As a safety measure, and to avoid repeated overloads on the inputs of the

device, we recommend performing configuration operations only when the
device is disconnected from all dangerous voltages.

3 USE

3.1 COMMISSIONING

Insert the batteries supplied with the device as follows:

1. Using a screwdriver, unscrew the screw of the battery compartment cover
(item 1) on the back of the housing and open it.

2. Plac e the 4 batteries in the compartment (item 2), taking care to get the
polarities right.

3. Close t he batt ery compartment cover and screw it to the housing.

Figure 6 : the battery compartment cover

3.2 STARTING UP THE CLAMP MUL TIMETER

The switch is s et to OFF. Turn th e switch t o the funct ion of your choice. T he whole
display lights (all symbols) for a few seconds (see §1.3

), then the screen of the
function chosen is displayed. The clamp multimeter is then ready to make
measurements.

Clamp Multi me ter METRACLIP 8 7 English

3.3 SWITCHING THE CLAMP MULTIMETER

The clamp multim eter can be switched off either manually, by setting the s witch to
OFF, or automatically, after ten minutes with no action on the switch and/or the
keys. Thirty (30) seconds before the device is switched off, an audible signal
sounds intermittently. To re-activate the device, press any key or turn the switch.

3.4 CONFIGURATION

As a safety measure, and to av oid repeated overloads on the inputs of the device,
we recommend performing configuration operations only when the device is
disconnected from all dangerous voltages.

3.4.1 De-activation of automatic switching off (Auto Power OFF)

To de-activate automatic switching off:

In the OFF position, hold the

key down while turning the switch to

, until the "full screen" display ends and a beep is emitted, to enter the

configuration mode. The

symbol is displayed.

When the ke y is released, the device is in the voltmeter function in
the normal mode.

The return to Auto Power OFF takes place when the clamp is switched
back on.

3.4.2 Programming of the current threshold for the True INRUSH

measurement

To program the triggering current threshold of the True INRUSH measurement:

1. in the OFF position, hold the

ke y down while turning the switch to

, until the "full screen" display ends and a beep is emitted, to enter the
configuration mode. The display unit indicates the percentage overshoot to
apply to the measured current to determine the measurement triggering
threshold.

Remark : The value stored by default is 10%, representing 110% of the established
current measured. The possible values are 5%, 10%, 20%, 50%, 70%, 100%,
150%, and 200%.

2. To change the threshold, press the

key. The value flashes: each

press on the

key displays the next value. To record the chosen

threshold, apply a long press (>2s) on t he

key. A confirmati on beep is

emitted.

22

English Clamp Multimeter METRA CLIP 87

To exit from the programming mode, turn the switch to another setting. The chosen
threshold is stored (emission of a double beep).

Note: The s tarting current measurement triggering threshold is fixed at 1% of the
least sensitive range. This threshold is not adjustable

3.4.3 Programming t he rate of recording in memory

1. In the OFF position, hold the

ke y down while turning the sw itch to

, until t he end of the "f ull sc reen" display and the em ission of a beep,
to enter the configuration mode. The display unit then indicates the
interval of recording of the data in memory.

Remark: the default value is 60 seconds. Possible values range from 1 second to
600 seconds (10 minutes).

2. T o change the re cording interv al, press the

key. The right-hand digit

blinks: each press on the

key increments its value. To go to the next

digit, apply a long press (>2s) to the

key.

When the desired unit is displayed, turn the switch to another setting. The unit
chosen is stored (emission of a double beep).

4 MAINTENANCE

The instrument has no parts that can be replaced by personnel who are not trained
and approved. Any non-approved repair or other work, or replac ement of a part by
an "equivalent", may severely compromise safety.

4.1 CLEANING

•

Disc onnec t everything connected to the device and set the switch to OFF.

•

Use a s oft cloth moistened with soapy water. Rinse wit h a damp cloth and

dry quickly using a dry cloth or forced air.

•

Dry perfectly before putting back into use.

4.2 REPLACEMENT OF THE BATTERIES

The symbol indicat es that the batteries are spent. When this symbol appears
on the display unit, the batteries must be replaced. The measurements and
specifications are no longer guaranteed.

To replace the batteries, proceed as follows:

1. Disc onnec t t he measurement leads from the input terminals.

2. Set the switch to OFF.

3. Use a s c rewdriver to unscrew the screw securing the battery compartment
cover to the back of the housing and open the cover (see §3.1

).

4. Replace all o f the batteries (see §3.1).

5. Close the cover and screw it to the housing.

4.3 METROLOGICAL CHECK

Like all measuring or testing devices, the instrument must be checked regularly.
This instrument should be checked at least once a year. For checks and
calibrations, contact one of our accredited metrology laboratories (information and
contact details available on request), at our GOSSEN METRAWATT subsidiary or
the branch in your country.

4.4 REPAIR

For all repairs before or after expiry of warranty, please return the device to your
distributor.
