7
. Battery level indicator.
When this indicator becomes " ", the battery in the transmitter is
not high enough and must be replaced immediately.
8
. Voltage value display which shows the external voltage value.
The transmitter can detect the DC or AC voltage of the circuit connected to
the terminals of the transmitter, the detecting range of the transmitter is 12V
dc to 600V dc, or 12V ac to 600V ac at 50Hz -60Hz.
If the voltage being detected is < 12V, " " will be shown on
this voltage value display.
Note:
If the voltage between the two lines which are connected to the two
terminals of the transmitter is a DC voltage, the transmitter will
display the absolute value of this voltage.
