Mass is measured with weight, a graduated cylinder, and a scale.
a scale, what else would you use?
A spring scale :)

Pmmc meter are most accurate instrument for DC measurement however they are unable to measure the AC quantity. The working principle is as follows: a moving coil is free to move in a external static magnetic field. And the pointer moves according to the interaction of two fields, field of static mag. and that of measuring quantity. Now in case of it is impossible to produce a sustained magnetic field, that's why we can not use PMMC to measure the ac.
Produce of series type Ohmmeter using PMMC of Ifsd:100uA for range of 0-20kohm?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.

it is an instrument for measuring a person
i dont realy know but i think it is a scale that is used on an orthophoto
yes
In PMMC meter or (D'Arsonval) meter or galvanometer all are the same instrument, a coil of fine wire is suspended in a magnetic field produced by permanent magnet. According to the fundamental law of electromagnetic force, the coil will rotate in the magnetic field when it carries an electric current by electromagnetic (EM) torque effect. A pointer which attached the movable coil will deflect according to the amount of current to be measured which applied to the coil. The (EM) torque is counterbalance by the mechanical torque of control springs attached to the movable coil also. When the torques are balanced the moving coil will stopped and its angular deflection represent the amount of electrical current to be measured against a fixed reference, called a scale. If the permanent magnet field is uniform and the spring linear, then the pointer deflection is also linear

That depends on the instrument.
