Product Description

By entering your model number, you can make sure that this fits.

HIGH QUALITY:The resistance value does not change with temperature, making the resistance measurement result more accurate. It is precisely made of high quality manganese copper wire.

KNOB SWITCH: Measurement is made easier with this knob switch.

CHOICE OF RESISTANCE: X0. 1, X1000X100X10, X1000X100X10, X1000X100X10, X1000X100X10, X

0-9999 as a parameter. 9; 0 is the smallest step size. 1st grade accuracy level 1

MUCH SAFER: The circuit's insulation resistance to the case's metal part is greater than 50 M, effectively preventing the user from receiving an electric shock when touching the case.

This is not a laboratory product

3/5

Switches that are extremely sensitive and controls that are insecure. The rotary switches are actually just wipers that move across the circuit board's traces, making them extremely unstable. The resistance changes simply by touching the knobs. SMT resistors are used inside, and they are very small. I doubt they'll be able to carry even a single watt of power. The jacks are simply binding posts, not banana jacks. This unit had to be returned due to its poor quality. Controls that are insecure.
