4.2. DESCRIPTION OF FUNCTION KEYS
4.2.1. HOLD
key
Pressing the
HOLD
key freezes the value of the measured quantity on the display. After
pressing this key, the message
“
HOLD
”
appears on the display. Press the
HOLD
key again
to exit the function. Press and hold the
HOLD
key for a long time in order to
activate/deactivate the display
’
s backlight. This function is activated in any position of the
rotary switch and is automatically deactivated after approx. 10s.
4.2.2. RANGE
key
Press the
RANGE
key to activate the manual mode and to disable the Autorange function.
The symbol
“
AUTO
”
disappears from the upper left part of the display. In manual mode,
press the
RANGE
key to change measuring range: the relevant decimal point will change
its position. The
RANGE
key is not active in Frequency measurement and Duty cycle test
and in positions
and
(HT62) of the rotary switch. In Autorange mode, the
instrument selects the most appropriate ratio for carrying out measurement. If a reading is
higher than the maximum measurable value, the indication
“
O.L
”
appears on the display.
Press and hold the
RANGE
key for more than 1 second to exit the manual mode.
4.2.3. MAX
MIN
key
Pressing the
MAX MIN
key once activates the detection of maximum and minimum values
of the quantity being tested. Both values are constantly updated and are displayed
cyclically every time the same key is pressed again. The display shows the symbol
associated with the selected function:
“
MAX
”
for maximum value and
“
MIN
”
for minimum
value. The
MAX MIN
key is not active when the HOLD function is activated. Pressing the
MAX MIN
key the “AUTO” and bargraph disappears. The
MAX MIN
key is not active in
Frequency measurement and Duty cycle test and in positions
and
(HT62) of the
rotary switch. Press and hold the
MAX MIN
key for more than 1 second or turn the selector
to exit the function.
4.2.4. Hz%
key
Press the
Hz%
key to select frequency measurement and duty cycle test in positions
V
Hz%, 10AHz%
,
mA
(AC),
A
(AC) and
Hz%
of the rotary switch. The frequency
range is different in the different positions.
4.2.5. REL
key
Press the
REL
key to activate relative measurement. The instrument zeroes the display
and saves the displayed value as a reference value which subsequent measurements will
be referred to. The symbol
“
REL
”
appears on the display. This function is not active for the
following measurements: Hz, Duty Cycle, Continuity Test, Diode test and Temperature
(HT62). Pressing the
REL
key the “AUTO” and bargraph disappears Press the key again
to exit the function.
4.2.6. MODE
key
Pressing the
MODE
key allows selecting a double function on the rotary switch. In
particular, it is active in position
and
(HT62) to select diode test,
continuity test, capacitance measurement (HT62) and resistance measurement, in position
°C°F
(HT62) to select temperature measurement in °C or °F, in positions
V
Hz%
and
LoZV
for AC or DC voltage selection and
mA
,
A
to select AC or DC
measurements
