Physics | Current Electricity | Electricity and Magnetism A. Easy-Read Meter A
Use the meter to measure the current through the Helmholtz Coils. The attachments are colour-coded and their sockets are arranged to help students grasp the concepts of shunts and multipliers. The basic unit has an input impedance of 100kO. The resolution is 0.01 and the accuracy is ±2%. Supplied with a PP3 battery that gives a useful life of over 1000 hours, the Easy-Read displays ‘LO BAT’ when the battery needs to be replaced.

Easy-Read Attachment
The black shunts adapt the Easy-Read for current measurement and their sockets are found in the ends of the attachment (current passes through). The orange multipliers adapt the Easy-Read for voltage measurements, and have their sockets on the front of the attachment (voltage is measured across a circuit component). The 20V d.c. attachment has an input impedance of 10MO.
At least one of the following attachments should be bought for each Easy-Read meter.
