• Selector switch : turn the switch to select the appropriate function and range.
• Needle : will indicate the measured value.
• Before starting, check that the needle is set to 0. If it isn't, adjust its position
by turning the adjusting screw.
During the measurement:
- If the needle stays to the left on position 0, this means that the position of the
test plungers is incorrect; reverse the position and test again.
- if the needle stays to the right on position 300 (or 60 or 12), this means that
the measured value is higher than the maximum value of the selected range.
You must remove the test plungers from the circuit. Then select a suitable
rating and test again.
Always start with the highest rating if you are in doubt about the value to be
measured.
