4、 Each part and name of the instrument (as shown in the following figure)

4.1 Power Supply

Note: For probes that distinguish between transmitting and receiving ends, such as TSTU32, they should be inserted into the transmitting and receiving sockets.

The instrument is powered by 3 AA batteries and the battery level will be indicated on the screen. The Coulomb meter is used for power measurement, so it defaults to a fully charged new battery when there is a power outage. Twist open the back cover with a coin or key to replace the battery.
