current measurement circuit.
2) If the effective value of the measured current AC + DC is within the range from 200
mA to 10 A, only 10A and LO terminals are allowed to be used in the measurement.
3) When the measurement of current is conducted, before the multimeter is powered
on, be sure to select the proper current input terminals based on the estimation.
4) The current input to the terminal 10 A must not exceed 11 A; otherwise, the internal
fuse inside the multimeter will blow; and the current input to 200 mA terminal must not
exceed 500 mA; otherwise, the current input fuse on the back panel will blow.
IEC Measurement Category II Overload Protection
To protect against the danger of electric shock, this product provides overload
protection for line-voltage mains connections meeting both of the following conditions:
1 . The HI and LO input terminals are connected to the mains under the Measurement
Category II (as described below) conditions.
2 . The mains are limited to a maximum line voltage of 300 VAC.
Warning: IEC Measurement Category II includes electrical devices connected to
mains at outlet on a branch circuit. Such devices include most small appliances, test
equipment, and other devices that plug into a branch outlet socket.
This product can be used for such measurements: HI and LO inputs are connected to
mains of such devices (up to 300 VAC), or to the branch outlet. However, this product may
not used with its HI and LO inputs connected to the mains in permanently installed
electrical devices, such as the main circuit-breaker panel, sub-panel disconnected boxes,
or permanently wired motors. Such devices and circuits are subject to over voltages that
may exceed the protection limits of this product.
Notes: Voltages above 300 VAC can be measured only in circuits that are isolated
from mains. However, transient over voltages are also present on circuits that are isolated
from mains. This product is designed to safely withstand occasional transient can over
voltages up to 2500Vpk. Do not use this equipment to measure circuits where transient
overvoltages could exceed this level.
Environment related notes
This product complies with the WEEE Directive (2002/96 / EC) marking requirement.
The affixed product label (see below) indicates that you must not discard this electrical /
electronic product in domestic household waste.
