300/5A 240° Long Scale Meter / Moving Instrument DC Ammeter
In analog meters, the interface is application specific and can display any unit of measure, with nearly any input signal that is representative of the process. An analog meter can display speed, frequency, Voltage, current, temperature, strokes per minute, or feet per second. The actual input signals are analog voltage or current, in either AC or DC. An example is 0 to 10 volts DC, four to 20 milliamps DC or 0 to 100 volts DC. Digital meters operate in much the same way; however digital meters will often-times also include digital scaling of the display relative to the input signal.

Note: Please mention the voltage and watts when ordering. Reactive power meter upon request.
All cases at least dust and splash water-proof.
All cases are made of strengthened self-extingushing PPO With a high hit-resistance and a maximum electric isolation
Accuracy class :
AC, DC Voltmeters and Ammeters comply with the accuracy class 1.5.
The power meters comply with accuracy class 1.5.
The frequency meters comply with accuracy class1.0.
The maximum-demand meters comply with accuracy class 3.0.
The power factor meters and synchroscope meter comply with accuracy class 2.5.
Insulation test :
The insulation test is carried out at a voltage of 2KV, 50Hz 1 min and applies for instruments with the full scale deflection up to 650V. Other standards comply with IEC61010-1.
All instruments operate trouble-free at room temperature ranging from -25 to + 40.
The Max. Voltage to earth Voltmeter-The upper range voltage (full scale deflention)
Ammeter-The Voltage of the main power supply.
The meter used shall be keep cleaning. The user shall be made aware that, if the meter is used in a manner not specified by the manufacturer, the protection provided by the meter may be impaired.
The instruments are calibrated for vertical mounting, unless other positions such as horizontal or inclined at any specified angle to the horizon. can be provided upon request (in this case, specify angle of inclination, please) The accuracy class refers to the specified mounting angle only.
