2. INTRODUCTION

The METRAFLEX are AC current probes utilising Rogowski principle. They can be used to measure AC current up to 300A 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 300M), proportional to the current being measured with three selectable ranges.

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.

Battery status is indicated by an orange LED on the front of the integrator module. This LED will flash one time when the unit is switched ON. The length of time the LED is lit will increase as battery life decreases. Continuous lighting of LED indicates low battery and requires batteries to be replaced.

Should you suspect a depleted battery or the low battery LED blinking, proceed as follows.

1. Turn "OFF" all power to the unit and measurement circuits.
2. Set the probe selector switch to the "OFF" position.
3. Remove the flexible current probe from around the conductor of your measurement circuit. Disconnect the output from the measuring unit. Remove the external power supply cable.
4. Rotate the battery lock screw (1/4 turn) until it aligns with the unlock symbol. The battery cover can now be removed.
5. Install the replacement batteries into the battery holder. Observe correct polarity.
6. Replace the battery cover and turn the battery lock until it aligns with the lock symbol.

4.2 CONNECTING TO MEASURING DEVICE

Read safety section of instructions before operating this product.

METRAFLEX 300M: 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.

4.3 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.

Always connect electronics unit to measuring device before installing the flexible measuring head.

Open the probe coupling and slip the measuring head over the conductor carrying the current to be measured.

Close the probe coupling such that it visibly and audibly snaps into place.

An accurate measurement is assured under the following conditions:

- The conductor is centred within the measuring head.

- The measuring head forms a perfect circle.

- The probe coupling is not located close to other conductors carrying high current.

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.

To obtain correct results set the scaling factor on the meter or analyser for each measurement channel corresponding to the selected measuring range; see table under SPECIFICATIONS.

When measuring active power you also must observe the direction of the current flowing through the measuring head. Check the correct polarity at the power analyzers based on the vector representation of voltage and current, or by the polarity of the values for active power. These have to be positive for consumer measurements.

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. WARRANTY

Your METRAFLEX is guaranteed for two years from the date of purchase against defective material or workmanship. If the unit fails during the warranty period, we shall at our discretion, repair or replace it with a new or reconditioned unit provided we are satisfied that the failure is due to defective material or workmanship. To make a claim under warranty, the probe should be returned to us, postage prepaid, with a description of the defect. The use of a battery or external power supply, other than that specified invalidates this warranty.

Goods alleged by the buyer to be defective shall not form the subject of any claim for injury, loss, damage, or any expense howsoever incurred whether arising directly or indirectly from such alleged defects other than death or personal injury resulting from the seller's negligence.

No condition is made or to be implied nor is any warranty given or to be implied as to the life or wear of goods supplied or that they will be suitable for any particular purpose or for use under specific conditions, notwithstanding that such purpose or conditions may be made known to the seller.
