AUTOMATIC MEASUREMENT RANGE SELECTION
When
AUTO
shows on the display, the device will automatically select the ideal measurement range. Change this function to manual
selection by pressing the
RANGE
button. The measurement range will increase every time the button is pressed. After reaching
the maximum range, the device switches again to the minimum range. The maximum and selectable measurement ranges of each
function are provided in tables throughout this description. Not all measurement functions have multiple measurement ranges. When
the approximate amounts are unknown, always select the highest possible measurement range at first. When the measured value
allows, adjust the range selection to achieve more accurate readings. Change back to automatic range selection again by pressing
the
RANGE
button.
RELATIVE MEASUREMENT
When the
REL
button is pressed, relative measurement will be performed. This stores the currently measured data and the display
will only show the deviance from the stored reference value. Displayed value = currently measured value – stored reference value.
If the display shows "0", it means that there was no change in the original value. Switch off this function by pressing the
REL
button.
Use of this function is practical in cases, when the display of the sensitive instrument does not, or does not definitely reset to zero. The
function cannot be activated for all measurements (frequency, power factor, diode test and continuity test, temperature, sound pressure
or luminosity measurements).
RECORDING OF MEASURED VALUE
By pressing the
HOLD
button - with the exception of Hz% mode - the device stores the value currently shown on the display. With a
repeated pressing of this button, the display will again show the currently measured value.
DISPLAY LIGHTING
Press the
LIGHT
button to turn on the backlight of the display. In order to save battery time, the backlight switches off after 5-10
seconds. By a double pressing of this button the backlight can be turned on for a shorter amount of time.
AUTOMATIC SHUT OFF
In order to extend battery life, the device switches to stand-by mode when no operations are carried out for a period of 10 minutes.
Switch back to operation mode by pressing the
LIGHT
button.
Disable the automatic shut off when working for longer periods. In order to do so, press and hold the
0
C/
0
F
buttons while switching the
device on. Release the buttons when the display turns on. When the function is disabled, the display will not show the "auto OFF" sign
(23). To change back to the "auto OFF" mode switch the device off and on using the dial button.
DC VOLTAGE MEASUREMENT
1. Connect the test leads to the device as shown on the figure. (red: "V", black: "COM")
2. Turn the dial button to the
V
mark.
3. Using the
FUNCTION
button select
DC
mode. The
DC
sign will appear on the display.
4. Connect the test leads in series connection with the measured circuit.
5. Power the measured circuit and read the displayed figure.
If the test leads were connected in opposite direction, the negative polarity sign (-)
will appear in the left side of the display.
Note:
Disable automatic range selection by pressing the
RANGE
button.
Then select the measurement range manually. Change back to automatic range selection by
pressing and holding the same button.
