6−2 DC Current Measurement
DANGER
●Do not make measurement on a circuit above 300V AC. This
may cause shock hazard.
●Do not make measurement with the battery compartment
cover removed from the instrument.
(1) Set the Function Selector switch to the " A" position DC should
be shown on the upper left corner of the display.
(2) With the transformer jaws closed and without clamping them onto
the conductor, press the Zero ADJ. Button for about one second
to zero adjust the display.
(3) Press the jaw trigger to open the transformer jaws and clamp them
onto the conductor under test and take the reading on the display.
Position the conductor at the center of the transformer jaws for
accurate measurement.
Note
◇During current measurement, keep the transformer jaws fully
closed. Otherwise, accurate measurement cannot be made. The
maximum measurable
conductor size is
approx. 24mm in
diameter.
◇ When the current
flows from the upside
(the display side)to
the underside of the
instrument,
the
polarity of the
reading is positive
and vice versa. (See
the figure at the
left.)

7. Other functions
7−1 Sleep Function
NOTE
The instrument consumes small amount of current even in the
Sleep (power-down) mode. Make sure to turn the Function
Selector switch to the "OFF" position, when the instrument is
not in use.
This is a function to prevent the instrument from being left powered on
in order to conserve battery life. This function causes the instrument
to go into the Sleep (powered-down) mode about 5 minutes after the
last switch or button operation.
To exit the Sleep mode, turn the Function Selector switch back to
"OFF", then to any other position, or press any button.
7−2 Data Hold Function
This is a function used to freeze the measured value on the display.
Press the Data Hold button to freeze the reading. The reading will
be held regardless of the subsequent variation in current under test.
The "
" symbol is shown on the upper right corner of the display
while the instrument is in the Data Hold mode.
To exit the Data Hold mode, press the Data Hold button again to
release it.
NOTE:
If the instrument in the Data Hold mode goes into "sleep," the Data
Hold function will remain effective when the instrument is powered
on again.
