ANALOG MILLI AMMETER
Indotech Analog Milli Ammeter – Analog Milli Ammeter (milliammeter) is a specialized type of ammeter designed to measure small currents in the milliampere (mA) range. It’s particularly useful when dealing with low-current circuits. The term “milliammeter” indicates that it measures current in milliampere (1 mA = 0.001 A). These instruments are commonly used in electronics, laboratories, research, and electronic circuit testing. Their sensitivity allows accurate readings even for tiny currents. So, the next time you encounter a delicate electronic circuit, remember the trusty analog milliammeter.
‘‘INDOTECH’’ Analaog Milli Ammeter have been found indespensible by Laboratories and Industrial Houses. All the components used in the manufacture of the instruments are selective and are designed to ensure long term accuracy and service. All parts/sub-assemblies are throughly inspected and gauged at all stages with utmost care by experts. analog milliammeter, analog milli ammeter
TYPE OF METERS : ANALOG MILLI AMMETER
- Analog milliammeters display the current reading using a mechanical pointer on a scale.
- Digital milliammeters provide a numerical readout on a digital display.
- Some multimeters have a dedicated milliammeter function.
Applications : ANALOG MILLI AMMETER
- Milliammeters are commonly found in electronic test equipment, such as multimeters and analog panel meters.
- They are used for tasks like measuring current through resistors, components, or specific sections of a circuit.
- In electronic design and troubleshooting, milliammeters help verify proper current flow and diagnose faults.
PARAMETERS AVAILABLE :

Purpose and Measurement:
- A milliammeter is specifically calibrated to measure currents in the milliampere range (typically from 0 mA to a few hundred milliamperes).
- It is commonly used in electronic circuits, laboratories, and various applications where precise current measurements are necessary.
TESTS : Following tests are performed as per BIS 1248-03
| Test | Result |
| VIBRATION TEST | The meters are subjected to vibrations. This test ensures that if there is any loose component, it will be detected before the meter is passed. |
| LIFE TEST | The meter is subjected from zero to full scale and the counter meter records the number of operations. |
| OVER LOAD TEST | The meter is over loaded 120% of its rated capacity for 2 hours. |
| HIGH VOLTAGE BREAKDOWN TEST | The meter should withstand 2kV, AC, if applied between electrical circuit and any metallic point of the meter for 1 minute. |
| INSULATION RESISTANCE TEST | BIS1248-03 specifies that the insulation resistance should be above 5 mega ohms. The test is performed accordingly. |
| ACCURACY TEST | The accuracy test is performed as per BIS 1248-03.The error is calculated on the basis of full scale deflection of the meter. |
