4.2. FUNCTION KEY DESCRIPTION
4.2.1. H key
By pushing “
H
” key the parameter measured value is frozen on the display and the symbol
”HOLD” appears on it. This mode is disabled by pushing “
H
” key or moving the rotary
switch.
4.2.2.
key
Keep pressed the “
H
” key for the backlight activation. This light could help the operator
reading the display while he’s measuring in dark sites. For sake of battery saving after 10
seconds the light is automiatically switched off.
4.2.3. MODE key
By pushing
MODE
key the selection of double measured functions which are present at
display is possible. In particular this key is active in
Ω
CAP
position to select among
resistance test, diode test, continuity test and capacitance test, and in
Temp
position to
select between °C and °F in temperature test and in
60A
,
600A
position (only
HT9015) to select between AC or DC current measurements.
4.2.4. MAX/MIN key
By pushing
MAX/MIN
key the parameter maximum and minimum values are measured.
Both values are stored in memory and they can be shown cyclically when pressing “MIN
MAX” key. The display shows the symbol linked to the selected function: “MAX” for
maximum value, the symbol “MIN” for minimum value. This mode is activated on each
measurement except for continuity test, diode test capacitance test, frequency test and
duty cycle test. The bargraph disappear in the functions where the MAX/MIN feature is
active.
This mode is disabled keeping pressed
MAX/MIN
key or moving the rotary switch.

positions, the
Hz%
key permits to select the frequency test (Hz) or the duty cycle test (%)
4.2.6. PK/REL key
With rotary switch on
,
,
CAP
and
DC current
(only HT9015) the
PK/REL
key
permits to perform the zeroing of value at display and a relative measurement of the
parameter under test.
By pushing
PK/REL
key the instrument takes the actual parameter’s value as on offset
and performs a relative measurement. The relative value is displayed, it’s calculated as
actual value – offset value, the “REL” symbol is shown at display and the bargraph is
disabled.
This mode is disabled for resistance test, continuity test, AC current test, temperature test,
frequency test, duty cycle test and diode test and with
MAX/MIN
mode activated. This
mode is disabled pressing
PK/REL
key or moving the rotary switch

positions (only
HT9015) the
PK/REL
key permits to activated the maximum peak measurement of
AC
current
(calculated with response time <10ms). The “
P
” symbol is shown at display and
the value is continuously updated by the meter.
This mode is disabled pressing
PK/REL
key or moving the rotary switch
