and prevents a slipping of the hand inadvertently to the front, unsecured area of the clamp-on
ammeter.
Do not apply around or remove from HAZARDOUS LIVE conductors.
Prior to usage and measurement check that the instrument is In perfect working order,
for example At a known current source.
Select the measuring range priori to connection of the instrument to the UUT (unit under
test).
Before selecting a new function or measuring range the instrument must be disconnected
from any circuit.
Use the instrument only In clean and dry surroundings. Dirt and moisture reduce the
effectiveness. Dirt and moisture reduce the effectiveness of the insulation with consequent danger
of electrical shock, especially when dealing with high voltages.
The respective accident prevention regulations established by the Professional associations
are to be strictly enforced At all Times regarding tasks executed under voltage or In proximity of
parts under voltage.
AC current measurement
1)
Switch on the instrument
2)
Select measurement range A
~
3)
Open the clamp and surround the conductor of the current circuit to be measured
Make sure that the current converter (1) is completely closed as this may result in measurement
errors.
4)
In case of range overflow, “OL” is displayed
5)
Read the measured value on the display.
Key “MIN/MAX” is used to display minimum or maximum value during a measurement.
Voltage measurement
Caution! Never apply more than 600V AC/DC to the test Leeds (instrument). If these
threshold is exceeded the result could be serious personal injury or damage to the instrument.
