2. OPERATING INSTRUCTIONS
2.1 Setting the full and cut-off voltage
2.1.1 Set the full voltage:
Step 1: In the normal display interface(like fig. 1), long
press the button until the LCD screen displays the
interface like fig. 2, then release the button
Step 2: SET character blink present it is the setting status
of full / cut-off voltage, long press the button until the
LCD screen display the interface like fig. 3, then release
the button.
Step 3: At this time, the battery symbol displays full grids
of energy and this means the full voltage setting status,
factory default the full voltage is 020.0V, the numerical
code circulation flashing from the low bit to the high bit
show that the current setting digit, short press to set
the digit; please pay attention to that, as the full voltage
setting value has 4 digits, but the numerical code has only
3 digits.
So the setting is divided into two parts: low bit (fig. 3)
+high bit (fig. 4). For example, the default full voltage is
020.0V, then the display state is 20.0V to 020V low and
high cyclic switching display. If you need to set the full
voltage is 199.0V, then please set the low bit to 99.0V,
when the cycle reaches the high bit, it will display 099V,
and only the highest zero bit flickers to prompt you it can
be settled. Setting the high bit to 199V represents the full
voltage is 199.0V.
2.1.2 Set the Cut-off voltage:
Step 1: After you set the full voltage, you will need to
press the button longer until LCD shows the interface of
Fig. 5, then release the button;
Step 2: At this time, the battery symbol shows the zero-
grid to indicate the cut-off voltage setting state, the
default cut-off voltage is 016.0V, the setting method is the
same as above; the cut-off voltage is 0.8 times of the full
voltage by default, after setting the full voltage, the cut-off
voltage is automatically generated in the relationship of
0.8 times; otherwise, you can reset it;
After all the above settings are completed, long press of
the button until the settings are saved and exit the setting
status, restore the normal display interface.
2.2 Current range setting
Step 1: In the normal display interface, long press of the
button until the LCD shows the interface of Figure 2, then
release the button, short press of the button again switch
to the interface to Figure 7, it indicates that this state is
the current range setting state.
Step 2: Longer press of the button until the LCD shows
the interface of Figure 8, then release the button, short
press the button again to switch the current range. This
meter provides four current ranges, factory default is
100A, choose the corresponding range according to the
shunt.
Step 3: After the current range setting is completed, long
press the button until the settings are saved and exit the
setting status, restore the normal display interface.
Step 2: Longer press of the button until the LCD shows
the interface of Figure 8, then release the button, short
press the button again to switch the current range. This
meter provides four current ranges, factory default is
100A, choose the corresponding range according to the
shunt.
Step 3: After the current range setting is completed, long
press the button until the settings are saved and exit the
setting status, restore the normal display interface.
