What is the error in measurement of current by Clamp Meter (Tong Tester)?

When I am measuring the current (in the range of 10Amps) in a wire by a clamp meter, I am getting a difference of 1Amps in the measured value depending upon the location of the wire inside the CT. If the wire is held near the clamping point (but completely inside the core) the meter shows higher value than if the wire is held at the centre of the core.

The difference is how well the magnetic field from the current in the wire couples to the magnetic core of the clamp part of the meter. Better coupling will give a higher reading.

KMI Batt O Meter Musician Battery Tester $29.95 The KMI Batt O Meter Musician Battery Tester is a small device that allows musicians to test the remaining hours of battery life and voltage of 9 volt batteries while they are still inside gear with a 1/4-inch plug. The Batt-O-Meter works with almost any active instrument pickup or effects unit (stompboxes and other floor effects) that require a 9 volt battery to operate, and is turned on when a standard 1/4-inch cable is plugged into it. The Batt-O-Meter can test stand-alone batteries: 9V, 1.5V (AAA, AA), and 3V. It does this, by automatically placing the battery under an appropriate load to simulate real world usage. It works with Alkaline, Rechargable, and old school Carbon-Zinc batteries.

Batt-O-Meter measures the Voltage and Current to let you know how many more hours the battery will work. A micro-processor within the unit allows the device to intelligently determine the different loads that can be put on the battery and calculate the power in hours remaining. This eliminates the need for extra buttons and adaptors, and makes the Batt-O-Meter simple to use. What is the Power Probe? The Power Probe is not your normal 1/4 inch plug. It is a gold plated 1/4' plug specially designed to allow the Batt-O-Meter to test the unit without turning it on. This allows for far more accurate readings with a wide array of devices. Can the Batt-O-Meter check its own battery? Yes! The B

The calibration is now complete. OPERATION: • Remove the protective cap. • Turn the meter on by pressing the ON key. • Immerse the probe in the solution to be tested. • Stir gently and wait for the reading to stabilize. • After use, rinse the electrode with water to minimize contamination. • Always replace the protective cap after use. Note: if the reading is overrange, T75 will display ''1'' while T76 shows ''. . .''. PROBE REPLACEMENT: The probe can be easily replaced in the following way: • Remove the protective cap. • Unscrew the plastic ring on the top of the probe. • Pull out the MA73075 (or MA73076) probe and replace it with a new one (aligning the colored pin towards the LCD side). • Make sure the gaskets are in place before screwing back the plastic ring.
