In order to prevent any danger, always measure a present volt-
age first without low-pass filter (high-frequency suppression) to
detect a dangerous voltage.
5.1.9 The “RANGE” key
5
has two functions:
RANGE (measuring range):
The “RANGE” key

can be
used to switch to Hi (high sensitivity) or Lo (low sensitivity).
5.1.10 The “REL” key
6
has two functions:
REL function:
The REL key

to store the measuring result. At the same time,
the digital display
1
shows the “
HOLD
” symbol. If the measured value
exceeds the stored value by 50 digits, the change of the measured value
is indicated by the display ashing and an acoustic signal. (Changes of
measured values between AC and DC voltage / current will not be rec-
ognized). Press the key again to switch the device back to the measuring
mode.
Display illumination:
Press the key for approx. 2 seconds to enable or disable the display
