EDM80 Desk Stand Meter
Product Code : SCL-EAE-11357
Quick answer: The EDM80 Desk Stand Meter is an analog DC voltmeter with a 0-3 V range, a moving-coil movement and accuracy class 2.5, mounted on an inclined desk stand with red and black terminals. It suits low-voltage measurements such as cell voltages and voltage drops in simple circuits. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
The EDM80 is a low-range DC voltmeter: full-scale deflection corresponds to 3 V, which covers one or two dry cells and the voltage drops across lamps and resistors in simple school circuits. Like any voltmeter it is connected in parallel with the component under test, with the red terminal to the more positive point.
Its accuracy class of 2.5 means the error should not exceed 2.5 percent of full scale, about plus or minus 0.075 V anywhere on the 0-3 V scale. That makes it a useful example when students discuss why readings near full scale are proportionally more reliable than readings near the bottom of the scale.
- Confirm that the circuit voltage will not exceed 3 V DC.
- Check that the pointer rests at zero before connection.
- Switch off the circuit and connect the meter in parallel across the component, red to positive.
- Switch on and read the pointer against the graduated scale, estimating between divisions where needed.
Key features

Frequently asked questions
What is the range of the EDM80 desk stand meter?
It is a DC voltmeter with a range of 0 to 3 V and an accuracy class of 2.5.
What does accuracy class 2.5 mean for the EDM80?
The maximum error is 2.5 percent of full scale, about 0.075 V on the 3 V range, so readings in the upper part of the scale have the smallest relative error.
