What are the questions you may encounter?
Q: Can you turn off the meter automatically?
A: Yes, if there is no operation for 15 minutes when the meter is turned on, the meter will automatically turn off to save power.
Q：How to detect phase?
A：First, press and hold the "F" button to select the Phase function;
Second, Insert into the phase jack.
Prompting you to insert the red probe into the first phase jack when the"PA" symbol flashes (A blinks).
Prompting you to insert the red probe into the second phase jack when the"PAB" symbol flashes (A stays fxed while B is blinks).
Prompting you to insert the red probe into the third phase jack when the"PABC" symbol flashes (A and B stay fxed while C flashes).
Finally，The "P --- L" symbol indicates a left rotation in the phase sequence. The "P --- R" symbol indicates a right rotation in the phase sequence.
Note：Ensure completion of the test for all three wires within 1 minute. If the timeout error occurs, indicated by the "PABC" symbol with a flashing "P," return to phase sequence testing and retest.
Q: How to use the NCV function?
A: First, press the "F" button to select the "NCV" gear, and the "NCV" indicator will appear on the display;
Second, move the NCV sensor probe (located on the top of the device) close to the detection point;
Finally, if a strong AC electric field signal is detected, the screen will display "--H", and the screen will flash red and emit a rapid beeping sound;If a weak AC signal is detected, the screen will display "--L", and the screen will flash green and emit a slow beeping sound.
Q: How to use the TSM-192?
A: First, install the included batteries. Remove the rubber sleeve on the back of the multimeter, open the back cover of the batteries, put 2 AAA batteries into the battery compartment according to the polarity markings, and then re-cover the battery cover.
Second, turn on the multimeter in default auto mode, Press the "F" button to select the measurement of Phase, NCV and Live wire.
