Clamp type meter use
- 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.s
Clamp ammeters on what hold is
- As the ammeter moves, the current is constantly changing. After pressing the HOLD key, the current value at the instant is kepts
How to measure current clamp meter
- A table is actually a current transformer, the jammed wire is the equivalent of a transformer coils
How to use the clamp ammeters
- Clamp meter before the measurement was estimated the size of the current, and then decide which one range. If unable to estimate, can be the first to use the maximum range and appropriate for small files, with accurate readings. Cannot be used to measure small current file current. In order to prevent damage to the clamp type table.s
I would like to ask the relationship between the power of the water pump motor and the flow of water
- As long as the valve is fully opened, the motor is not overloaded, so that the frequency flow can be adjusted by using a flow transmitter or a pressure transmitter with frequency conversion. As long as the setting is good, the automatic control can be realized automatically.s
Air conditioning suddenly does not cool down, what's the matter?
- Two reasons for the non cooling of air conditioning: the voltage of power supply is not enough: the solution is to maintain normal supply voltage.s
How do you measure the capacitance with a caliper?
- If the current has been maintaining a value, then the capacitor is breakdown. But if there has been no current, there are two cases, one is the capacitance is too low (PF skin level), another current clamp meter resolution is not enough, in this case, capacitor is unable through current clamp type table to judge.s
Digital caliper table GT201, pliers table GT201 how to use?
- The method is that the digital caliper type GT201 is first drawn to the appropriate range of alternating current, and then the pliers are opened to clamp the tested wire and close the pliers,s
