Prokit's Industries 303-150NCS - Manual (Page 3)

DURING USE
• Never exceed the protection limit values indicated in specifica-
tions for each range of measurement.
• When the meter is linked to measurement circuit, do not touch
unused terminals.
• Never use the meter to measure voltages that might exceed
600V above earth ground in category II installations.
• When the value scale to be measured is unknown beforehand,
set the range selector at the highest position.
• Before rotating the range selector to change functions, discon-
nect test leads from the circuit under test.
• When carrying out measurements on TV or switching power
circuits always remember that there may be high amplitude volt-
ages pulses at test points, which can damage the meter.
• Always is careful when working with voltages above 60V dc
or 30V ac rms. Keep fingers behind the probe barriers while
measuring.
• Before attempting to insert transistors for testing, always be sure
that test leads have been disconnected from any measurement
circuits.
• Components should not be connected to the hFE socket when
making voltage measurements with test leads.
• Never perform resistance measurements on live circuits.
GENERAL DESCRIPTION
The meter is a handheld 3 1/2 digital multimeter for measuring DC
and AC voltage, DC current, Resistance, Diode, Transistor and
Continuity Test with battery operated.
The Back light of display is optional.
