3.The signal amplitude must also be greater than
the sensitivity level.
4.Determine that the amplitude level of the signal
to be measured is not greater than the input
voltage limit (25V DC/AC rms.).
5.Read the measure result directly from LCD
display.
NOTE
᧶
The input voltage should be between 1V
and 10V rms. ac. If the voltage is more than 10V
rms. Reading may be out of the accuracy range.
MEASURING FREQUENCY FOR CLAMP
1. Set the rotary switch to position.
2. Press the trigger to open transformer jaw and
to clamp one conductor only, making sure that
the jaw is firmly closed around the conductor.
3. Read the measure result of frequency of AC
current flowing through the transformer jaw
from the display.
NOTE:
Frequency range: 40Hz to 400Hz ( > 20A ).
MEASURING TEMPERATURE
1. Set the rotary switch at
q
C Position. The LCD
display will show “OL”.
2. Connect the red lead of“K” type thermocouple
into the“
V
:
Hz ”jack and the black lead of“K”
type thermocouple into the “COM” jack. The LCD
