Push-Buttons
RANGE:
Use the “
RANGE
” push-button to manually select a range.
Press and hold the “
RANGE
” push-button for two seconds to return
the meter to auto range mode.
The meter is in auto range mode when the “
AUTO
” indicator is on.
The range and units are displayed on the LCD.
MIN/MAX:
Press this button to scroll through the minimum,
maximum and average values. The minimum (MIN) reading is
displayed first and this mode calculates an average (AVG) of all
readings taken since the mode was activated. The meter beeps
when a new maximum or minimum reading is updated.
In the MIN/MAX mode, the primary display continues to show the
present measurement value.
Auto Power Off feature will be disabled automatically in this mode.
1mS Peak:
Press this button momentarily to activate the 1mS peak
hold mode to capture transient voltage or current signal events as
short as 1mS with its display resolution of 5,000 counts. The LCD
displays the “
1mS
” and “
MAX
” indicators at the upper left corner
and - and “
EXIT
” indicators in the on screen menu selection. In this
mode the meter will display the captured maximum value. Press
the - menu key and the LCD will now display “
1mS
” and “
MIN
”
indicators and “
+
” and “
EXIT
” indicators on screen. In this mode
the meter will display the minimum captured value. Press the “
+
”
menu key to capture a maximum value again if desired. The meter
will beep when a new maximum or minimum reading is updated.
Press either the “
1mS PEAK
” push-button or the “
EXIT
” menu key
to exit the 1mS peak hold mode. Auto Power Off feature is disabled
in this mode.
REL
∆
:
Use this push-button to set the meter to relative (REL
∆
)
mode and make relative measurements. The reference value for the
REL
∆
measurement can be a measured, or a programmed value. The
reference value appears in the secondary display and the difference
value appears in the primary display.
<REL
∆
to a Measured Value> - When you take the measurement
and the meter settles on the value, press this button. Subsequent
readouts will then be a difference from this reference value to the
new reading. This is useful for very low resistance values to
eliminate test lead resistance, or when observing a change from
a stable reading.
< REL
∆
to a Programmed Value> - Set the meter to the measurement
function and range you want and then press the “
REL
∆
“ push-button.
While the meter is in REL
∆
mode, press the “
MIN/M AX
” push-button
then the setup menu appears. Use the on screen menu selection
buttons to edit the desired reference value and then press the menu
button “
4
” for “
EXIT
” .
For subsequent readouts the programmed reference value is
subtracted from the actual measurement. The programmed
reference value is lost when the meter is turned off.
To exit REL
∆
mode, press the “
REL
∆
” push-button.
HOLD:
Press this button to turn the “
HOLD
” mode on or off. When
the hold mode is activated, the meter beeps, freezes the display and
displays the “
HOLD
” indicator on the LCD. Hold mode freezes the
display for later view.
Auto Hold - To activate “
AUTO HOLD
” mode, press the “
HOLD
”
push-button two times until “
A
” and “
HOLD
” indicators appear
on the LCD.
NOTE:
This mode is not available for capacitance measurements.
In this mode, the display automatically freezes and the meter beeps
when the measurement reading is stabilized. The display value will
be updated when a new measurement value is stabilized.
This mode is very useful when it is impossible for you to press the
“
HOLD
” push-button or see the meter display while probing and
taking measurements.
MEM:
Use the memory mode to store and recall measurement values.
Press the “
MEM
” button momentarily in order to activate the
memory mode. The display shows four menu selections: store, recall,
clear and exit.
STORE:
Select “
STORE
” to store the held value in the next available
m e m o ry location. The memory location number momentarily shows on
the secondary display. If no memory locations are available, FUL L s h ow s
on the secondary display for two seconds and nothing is stored. You must
clear the memory locations using the “
CL EA R
” key in order to store the
held value.
RECALL:
Select “
RECALL
” to review the stored value using the
menu key. The secondary display shows the value stored in that
location. Whenever you press “
+
” or “
-
” menu key, the next or
previous stored value will be shown in the primary display and
the secondary display momentarily shows the corresponding
memory location.
CLEAR:
Select “
CLEAR
” to clear all the stored values. When you
press the “
CLEAR
” key, the meter will ask you with the display of
“
You Sure
” along with the on screen menu selections of “
AC
”
(stands for All Clear), “
CLEAR
” and “
EXIT
”. When you press the
“
CLEAR
” key, the displayed value in the primary display is erased.
When you press the “
AC
” key, all the stored values are erased and
the word “
Done
” shows on the display. Press “
EXIT
” to exit the
memory mode without erasing the stored values.
EXIT:
Select “
EXIT
” to exit memory mode. You can also exit
memory mode by pressing “
MEM
” push-button or turning the
rotary dial position.
(Backlight):
Press the “
MEM
” ( ) push-button until the
backlight is turned on or off.
