Their compact size, low-profile design, and resistance to both rough handling and extreme temperatures make them essential tools for any electrician. Observe the difference between readings from these two types of instruments when measuring a distorted waveform that contains harmonic components such as those produced by inverters and switching power supplies. A pocket clamp meter that can use flexible sensors When connected to an optional flexible current sensor, the F can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires around which it was not possible to apply a clamp-on sensor in the past. Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter The F delivers all the functionality of a clamp meter and card tester in the form factor of the latter.

Be sure to insert the battery with the polarity correct. Handle and dispose of batteries in accordance with local regulations. To avoid electric shock when measuring live lines, wear appropriate protective gear, such as insulated rubber gloves, boots and a safety helmet.
Before using the instrument, make sure that the insulation on the test leads is undamaged and that no bare conductors are improperly exposed. Using the instrument in such conditions could cause an electric shock. Replace the test leads and probes with the specified Hioki Model L Do not use or store the in- Do not subject the instru- strument where it is exposed ment to vibrations or to direct sunlight, high tem- shocks.
Do not drop the instrument. Before using the instrument the first time, verify that it operates normally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative. Removable sleeves are attached to the metal pins at the ends of the test leads. In the CATII environment, if the tips of the test leads do not reach the measurement object, remove the rigid insulating sleeve before measuring.
For details on measurement categories, see "Measurement categories" in the instruction manual. When performing measurements with the sleeves attached, be careful to avoid damaging the sleeves. If the sleeves are inadvertently removed during measurement, be especially careful in handling the test leads to avoid electric shock.
To prevent an electric shock accident, confirm that the white or red portion insulation layer inside the cable is not exposed. If a color inside the cable is exposed, do not use the cable. NOTE Accurate measurement may be impossible in the presence of strong magnetic fields, such as near transformers and high-current conductors, or in the presence of strong electromagnetic fields such as near radio transmitters.
The indicator lights up when the remaining battery capacity is low. Replace the battery immediately. The and are different in the maximum range.
