must not
be attempted.
• Extreme care
must
be taken when measuring above 50 V, especially on live bus-bars.
• To measure voltage, the instrument must not be switched to a current or resistance
range, or to the diode check or buzzer position.
• Circuits
must
be de-energised and isolated before carrying out resistance tests.
• The rotary selector switch must only be turned
after
removing test connections.
• All external voltages
must
be disconnected from the instrument before removing the
battery.
• Test leads and prods
