My model number is UA9250. Would you like to ask how to distinguish the gears on the following table?! There are no letters on it. Some numbers will do. Please explain
Usage method(1) mechanical zeroing is necessary before measurement(2) select the appropriate range, first select large, then select small range, or see the nameplate value estimation.(3) when the minimum range measurement is used and the reading is not obvious, the number of turns to be measured shall be measured by the number of turns in the center of the jaw, and the readings = indication value * range / full bias * turn number(4) when measuring, the wire should be placed in the center of the jaw and close the jaw so as to reduce the error.(5) after measuring, place the change-over switch at the most measuring range.
Structure and principleClamp meter is essentially composed of a current transformer, a rectifier type clamp wrench and magnetoelectric force instrument.
The clamp type meter is a meter for measuring the current size of a running electrical circuit. It can measure current in the case of constant power.
