Read out the re-
sult.
The result is displayed on the screen for 20s.
The result can be recalled by pressing
ENTER
push-button.
Remarks:
- The result can be stored in the memory (see point 4.1).
- When many measurements are made in short time intervals, the meter may emit a large amount
of heat. As a result of this, the housing of the device may become hot. This is a normal phenomenon
and the meter is equipped with the protection against excessive temperature. After approximately 15
consecutive measurements of short circuit loop, wait until the instrument cools down. This limitation
results from the high current measurement and multi-functionality of the meter.
- Minimum interval between successive measurements is 5 seconds. This minimum interval requirement
is controlled by the meter. A next measurement can be made only when
READY!
message appears on
the screen.
