Fig. 3.5 Power Switch on Side Panel
When the 943B monitoring receiver is started, all settings of the last shutdown will be restored.
2) Shutdown
Step 1. Press and hold the power switch key in the lower middle of the side panel for about 3s, and the
shutdown interface will pop up. Select shutdown, and then the instrument will enter into the shutdown
process (the software and the hardware need to be processed before power off). After more than 10s,
the instrument will be shut down, and then the color of the power indicator light on the upper right of the
front panel will change from green to yellow.
3) Screen off
When users do not need to operate the instrument or view the test results for a long time, they can
choose to turn off the screen display, so as to reduce the power consumption of the complete machine
and extend the service life of battery power. This operation is similar to devices, such as smart phone or
PAD.
Step 1 . Press the power switch key in the lower middle of the side panel, release it immediately, and the
screen display of the instrument will be turned off. Perform the same operation again, and the screen
display of the instrument will be turned on.
Power cut of the instrument
When the instrument is in normal working state, it can be shut down by the power switch on the side
panel. If there is a problem with the instrument, press and hold the switch button for approximately 10s to
perform a forced shutdown. In case of an emergency, in order to avoid personal injuries, you can unplug
the power adapter or remove the battery to forcibly cut off power. Therefore, sufficient operating space
should be reserved when operating the instrument to facilitate direct shutdown when necessary.
3.1.5 Correct Use of connectors
Connectors are commonly used in various tests of the monitoring receiver, and the precautions for the
use of connector are as follows:
1) Connector check
When conducting connector inspection, anti-static wrist band should be worn. It is recommended to use
a magnifier to check the following items:

Whether the electroplated surface is worn or not and whether there are deep scratches;

Whether the thread is deformed;

Whether there are metal particles on the threads and the joint plane of the connector;

Whether the inner conductor is bent or broken;

Whether the screw sleeve of the connector rotates improperly.
