4.2. DESCRIPTION OF FUNCTION KEYS
4.2.1. Key
HOLD/REL
Pressing key
HOLD/REL
freezes the value of the measured quantity on the display. After
pressing this key, the message
“
HOLD
”
appears on the display. Press the key
HOLD/REL
again to quit the function. To save the value on the display, see § 4.3.4. Key
HOLD/REL
also allows quitting the programming menu, going back to the instrument
’
s main
measuring screen and restores the display
’
s illumination with instrument in Auto Power
OFF mode. Press longer the
HOLD/REL
key in order to activate/deactivate the relative
measurement on the selected function (see § 4.3.5).
4.2.2. Key
RANGE
Press key
RANGE
to activate manual mode and disable the Autorange function. The
symbol
“
Manual Range
”
appears on the display. In manual mode, press key
RANGE
to
change measuring range: the relevant decimal point will change its position and the full
scale value in the bargraph will change too. Key
RANGE
is not active in positions
,
,
Type K
and
60A , 600A , 1000A
. 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
“
OL
”
appears on the display. Press and hold
key
RANGE
for more than 1 second to exit the manual mode and restore the Autorange
mode.
4.2.3. Key
MODE/VFD
Pressing key
MODE
allows selecting a double function on the rotary switch. In particular, it
is active in position
:
CAP
for the selection of measurements for diode test, continuity
test, capacity test and measurement of resistance, in position
TypeK
for the selection of
temperature measurement in °C,°F or K,
Hz%
for the selection of frequency measurement
and duty cycle,
VAC+DC
for the selection of measurements
“
mV
”
and
“
V (AC+DC)
”
(see § 4.3.3),
V
Hz%
for the selection of AC voltage measurement, AC voltage
frequency and duty cycle of AC voltage,
LoZAC+DC
for the selection of AC voltage with
low impedance measurement (see § 4.3.8) “V
” and “V (AC+DC)”,
60A , 600A ,
1000A
for the selection of AC and DC current measurement for the selection of AC, DC and
A (AC+DC) current measurement. In position , pressing and holding (>2s) key
MODE/VFD
allows selecting the type of clamp, Standard (
) or Flexible ( ). In the
positions
VAC+DC
,
60A
,
600A
,
1000A
the longer press (>2s) of
MODE/VFD
key
allows to activate/deactivate the
VFD (Variable Frequency Driver)
measurement mode
(see § 4.3.9) in order to evaluate the AC voltage and current downstream variable
frequency drivers (inverters)
4.2.4. Key
IR/
(ECLIPSE), Key
(HT9025)
Pressing key
IR/
(ECLIPSE) allows displaying the multimeter section or the
combination mult thermographic image (see § 5.14). Pressing and holding (>2s)
key
IR/
(EXCLIPSE) or pressing key
(HT9025) allows turning on/off the internal
white LED illuminator (see Fig. 2
–
part 2).
4.2.5. Key /INRUSH
Key
/INRUSH
, given by the combination of keys
“
”
and
S
,
X
,
T
,
W
, allows entering the
instrument
’
s programming section in order to set both system parameters and those
connected to the detection of the thermographic image (see § 4.3.10).In the positions
60A
,
600A
,
1000A
the longer press (>2s) of the
/INRUSH
key allows to
activate/deactivate the AC inrush current of electrical machines with 100ms response time
(see § 5.11).
