･ Be sure to ensure the floating state for a battery circuit (measured
object) with voltage exceeding 30 Vrms, 42.4 Vpeak, or 60 VDC.
Connecting the instrument to a circuit exceeding 30 Vrms, 42.4
Vpeak, or 60 VDC may lead to electric shock.
･ To avoid electrical shock, be careful to avoid shorting live lines
with the measurement leads.
･ Do not measure the voltage of the voltage generator, as doing so
will cause an AC voltage to be applied to the output terminal of the
voltage generator, resulting in a hazard.
･ When a high-voltage battery has been measured and a low-voltage
battery is to be measured, short-circuit the measurement lead to
discharge the DC component cutoff capacitor of the 3560.
Otherwise, an overvoltage will be applied to the battery.

.5 Starting Measurement
Connect the lead to the measured object and read the measured value.
･ The value displayed may fluctuate if equipment generating magnetic
fields is located near the 3560, such as electric motors. If fluctuations are
observed, install the instrument in a location at a distance from the
equipment.
･ Objects having inductance of 5 μH or greater may produce incorrect
measurements.
･ Do not pile the 3560 instruments for measurement.
･ Note that if the tested object is placed on the instrument or close to the
indicator, measurements may fluctuate due to generated noise.
