5.1.2. DC Warning
The DC warning buzzer will beep continuously when DC voltage is
higher than 30 VDC on the test probes and the test button is not
pressed. The neon light "circuit live" will lit when the voltage on the
test probes is higher than 90 VDC and the test button is not
pressed.
5.1.3. AC Warning
The AC warning buzzer will beep continuously when AC voltage is
higher than 20VAC on the test probes and the test button is not
pressed. The neon light "circuit live" will lit when the voltage on the
test probes is higher than 65VDC and the test button is not pressed.
5.1.4. AC Measurement
The AC measurement is automatic on this instrument. As soon as
AC voltage is present on the test leads, the instrument will display
the AC voltage from 20 to 600 VAC on the linear scale.
5.1.5. Low Ohms Measurement 0-3/500
Always check for voltage before testing and measuring on a circuit.
This instrument is intended for measuring low  and Insulation
resistance on un-energized circuits only.
The first procedure to follow, is to zero the test leads and the fuse
resistance. The instrument is equipped with a zero  Knob. First,
short circuit the test leads by connecting them together, then press
the test button and adjust the zero  knob until the pointer is
precisely on the "=" of the 3/500 scale.
Use the mirror scale to be precise with the pointer. connect the test
leads to the circuit to be measured. For short test, press button and
keep pressed. For long test or hand free measurements, press and
turn the test button.
