2.2. FOR THE J93 AND J193 CLAMPS

Connect the clamp to the device, on one of the current inputs. Switch on the device. Adjust the zero by watching the display of the device and turning the zero adjustment knob until the device displays 0. 5000A 500A ZE RO Stop Test MARCHE SORTIE ZERO

QUALI STAR +21 Open the jaws of the clamp by moving the arm closer. Clamp the conductor carrying the current to be measured. There must be only one conductor in the jaws of the clamp. Gently close the jaws. In order to optimize measurement quality, centre the conductor as accurately as possible in the jaws. Read the measurement on the device. When the measurement is over, open the clamp and withdraw the conductor. Then disconnect the clamp from the device. Switch off the device.

The error in % is the ratio of the maximum variation to the mean value. 2: Test performed with a current of 300 A at 50 Hz. 3.4. TYPICAL CURVES

The power supply of the J93 clamp is provided by a 9 V alkaline battery (type 6LF22, 6LR61, or NEDA 1604). The nominal operating voltage is between 6.5 and 10 V. The battery life is 70 hours. The typical consumption is 11 mA. During the battery test, if the indicator lights, the clamp can be used. When the indicator no longer lights, the battery must be replaced (see §4.2).

The J193 clamp is supplied by the device to which it is connected. It delivers a voltage of 5 V ±0.25 V. The typical consumption of the clamp is 5.4 mA. 3.6. ENVIRONMENTAL CONDITIONS The device must be used under the following conditions: % RH

Electrical safety according to IEC 61010‑2‑032 for type A sensors. Maximum applicable voltage: 600V Cat. IV or 1000V Cat. III. 3.9. ELECTROMAGNETIC COMPATIBILITY (EMC) Emissions and immunity in an industrial environment in accordance with IEC 61326‑1, except for immunity to the electric field with a criterion B.28

Except for the battery, the instrument contains no parts that can be replaced by personnel who have not been spe- cially trained and accredited. Any unauthorized repair or replacement of a part by an “equivalent” may gravely impair safety. 4.1. CLEANING Disconnect the current clamp completely and switch it 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 clamp jaws as clean as possible. 4.2. REPLACING OF THE BATTERY (J93 CLAMP) Disconnect anything connected to the J93 clamp and switch it off. Spent batteries must not be treated as ordinary household waste. Take them to the appropriate recycling collection point. Then place the shim. Put the battery compartment cover back in the slide and push it in until you hear a click. 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 checking and calibration, contact one of our accredited metrology laboratories (information and contact details available on request), at our Chauvin Arnoux 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. Insert a tool, not more than 3 mm in diam‑ eter, in the hole in the battery compartment cover. Push to unlock the bat‑ tery compartment cover, then slide it off. Remove it completely by hand. Remove the battery and the shim from the compartment. Place the new battery in the compartment with the polar‑ ity as indicated on the label.
