UT207A/208A/209A Operating Manual
changeover of range shall be made during measurement is conducted to
prevent damage of the Meter.
● Do not carry out the measurement when the Meter’s back case and battery
compartment are not closed to avoid electric shock.
● Do not input higher than 1000V in DC or 750 V in AC between the two
Meter’s input terminal to avoid electric shock and damages to the Meter.
● When the Meter working at an effective voltage over 70V in DC or 33V rms
in AC, special care should be taken for there is danger of electric shock.
● Use the proper terminals, function, and range for your measurements.
● Do not use or store the Meter in an environment of high temperature,
humidity, explosive, inammable and strong magnetic eld. The
performance of the Meter may deteriorate after dampened.
● When using the test leads, keep your ngers behind the nger guards.
● To avoid electric shock, do not touch the bare wires, connectors, unused
input terminals or the circuit under testing during measurement.
● Disconnect circuit power and discharge all high-voltage capacitors before
testing resistance, continuity and diode.
● Replace the battery as soon as the battery indicator appears. With a low
battery, the Meter might produce false readings that can lead to electric
shock and personal injury.
● When servicing the Meter, use only the same model number or identical
