_______________________________________________________________ 1. SAFETY The following symbols appear on the products: Attention! Refer to Manual Double/Reinforced Insulation Do not apply around or remove from HAZARDOUS LIVE conductors without additional protective means. “Additional protective means” can be: - de-energizing the circuit - wearing protective clothing suitable for high voltage work. Do not dispose of this product as unsorted municipal waste. Contact a qualified recycler for disposal.
______________________________________________________________ The flexible current transformer is manufactured and tested in accordance with safety regulations IEC/EN 61010-1 / -031 /-2-032. If used for its intended purpose, safety is assured for the user, the device and the DUT. Read the operating instructions carefully and thoroughly before placing the device into operation. Observe and follow all points included therein. Make the operating instructions accessible to all users.
_______________________________________________________________ 2. INTRODUCTION The METRAFLEX are AC current probes utilising Rogowski principle. They can be used to measure AC current up to 3000A by being connected to an appropriate measuring device (multimeter, data logger, power analyser etc.). The flexible probe allows current measurements on conductors that are hard to reach. The probes provide an AC output voltage of 0…3V (METRAFLEX 3000/3001/3003) or 0…1.

_______________________________________________________________ 4. OPERATION 4.1 BATTERY INSTALLATION AND BATTERY STATUS Never replace batteries with flexible measuring head installed on conductor to be tested or output connected to a measuring device. Never operate the unit without the battery cover fitted. The METRAFLEX require two AA MN1500 LR6 alkaline batteries for operation. The battery compartment is accessed from the rear of the electronics enclosure.
______________________________________________________________ 4.2 EXTERNAL POWER SUPPLY Alternatively, the METRAFLEX can also be supplied by an external DC voltage source (except METRAFLEX 3000). The connection is made at the connector on the side of the electronics housing. Supply voltage range, see Technical Data.
_______________________________________________________________ 4.3 CONNECTING TO MEASURING DEVICE Read safety section of instructions before operating this product. METRAFLEX 3000: Plug the output cable of the current sensor into the voltage measuring input terminals of the multimeter (black to GND, red to V) and switch it to V AC. METRAFLEX 3001/3003: Plug each output cable of the current sensor to the current measuring input terminals “I” on the MAVOWATT|50.
______________________________________________________________ 4.4 CONNECTING TO THE CIRCUIT TO BE MEASURED It is strongly recommended to de-energize the circuits to be measured when making connections to the installation. If it is necessary to make connections on energized circuits they must be made by qualified and authorized personnel only observing the required safety precautions.. Never apply the probe around bare conductors with voltage levels over 1000V (CAT III) or 600V (CAT IV) to ground.
_______________________________________________________________ 4.5 MEASUREMENT To activate unit, move the rotary switch from the “off” position to the required measuring range. If the value of current being measured is unknown, first select the highest range and then reduce accordingly. The red and the orange LED might flash when the unit is switched on or when the measuring range is changed.
______________________________________________________________ 5. MAINTENANCE Do not use METRAFLEX if damaged. Always inspect the integrator unit, connecting cable, and flexible probes for damage before use. To avoid electric shock, keep the METRAFLEX clean and free of surface contamination. Use Isopropyl alcohol to clean the electronics unit and the probe. Make sure the flexible probe, connecting cable, and electronics enclosure are dry before further use. 6.
