4. operation 4.1. SAFETY INFORMATION 4.1.1. This instrument complies with class II, overvoltage CAT II-600V of the EN 61010-1 and EN 61010-2-032 standards. 4.1.2. Pollution degree 2 in accordance with IEC 664 indoor use. 4.1.3. If the equipment is used in a manner not specified, the protection provided by the equipment may be impaired. 88 DO NOT clamp around conductors with voltages equal to or exceeding 300V DC or 240V rms AC. 88 DO NOT clamp to bare or damaged conductors, to avoid possible physical injury. 4.2. PROCEDURE FOR MEASURING THE CURRENT IN AC AND DC CIRCUITS. 4.2.1. Insert the black banana plug into the COM socket and the red banana plug into the VΏmA socket of your multimeter (with a minimum input impedance of 10k ohms). 4.2.2. Set the power switch from "OFF" to the desired range, 40A (output: 1mV/A) or 400A (1mV/A) position. The green LED will illuminate to indicate the current clamp is switched on. 4.2.3. For current measurement below 40A, set the unit to the 40A range and set the multimeter to 200mV or 400mV range for AC current measurements. Alternatively set the multimeter to 200mV or 400mV DC range for DC current measurements. If the measured current exceeds 40A, set the unit to the 400A range. 4.2.4. When performing *DC current measurements, always press the "DC ZERO" button on the current clamp until the multimeter reads zero. Clamp the jaws around the current carrying conductor and interpret the reading according to the settings in 4.2.3. 4.2.5. When the 40A range is selected the measured current value (A) can be calculated using this example. If the multimeter reads 100mV, the measured current is 100mV divided by (10mV/A) = 10A. If the 400A range is selected, the measured current value (A) can be calculated using this example. If the multimeter reads 50mV, the measured current is 50mV divided by (1mV/A) = 50A. 4.3. NOTES ON DC CURRENT MEASUREMENT 4.3.1. In a DC circuit the output is positive when the current flows from the top face to the underside of the current clamp. Hysteresis can occur making it difficult to zero the current clamp. When this happens, open and close the jaws several times together with pressing the "DC ZERO" button to eliminate this effect. 4.4. MAINTENANCE ‰‰ WARNING! DO NOT attempt to repair or service unless you are qualified to do so and have the relevant calibration, performance test, and service information. To avoid electrical shock or damage to the meter do not get water inside the case. 4.4.1. Periodically wipe the casing and jaws with a damp cloth and mild detergent. DO NOT use solvents. 4.4.2. Turn off when not in use and remove the battery if stored for a long period of time. 88 DO NOT store in a place of high humidity or high temperature. 4.5. REPLACING THE BATTERY (fig.1) ‰‰ WARNING! To avoid electric shock, disconnect the 4mm banana connectors from any equipment before removing the battery cover. 4.5.1. When the battery becomes exhausted or drops below the operating voltage, the red LED battery symbol will be illuminated. 4.5.2. Open the battery cover by loosening the screw using a small cross head screwdriver. 4.5.3. Remove the old battery and insert the new one, observing the correct polarity clearly shown inside the compartment. 4.5.4. Replace the battery cover and secure with the screw. 4.5.5. Dispose of batteries according to local authority guidelines. Environment Protection Recycle unwanted materials instead of disposing of them as waste. All tools, accessories and packaging should be sorted, taken to a recycling centre and disposed of in a manner which is compatible with the environment. When the product becomes completely unserviceable and requires disposal, drain any fluids (if applicable) into approved containers and dispose of the product and fluids according to local regulations. Weee Regulations Dispose of this product at the end of its working life in compliance with the EU Directive on Waste Electrical and Electronic Equipment (WEEE). When the product is no longer required, it must be disposed of in an environmentally protective way. Contact your local solid waste authority for recycling information. Battery Removal - REFER TO SECTION 1.2 Under the Waste Batteries and Accumulators Regulations 2009, Jack Sealey Ltd are required to inform potential purchasers of products containing batteries (as defined within these regulations), that they are registered with Valpak's registered compliance scheme.
