1. adjust the zero point (zero indicator corrector): used for adjusting the needle indicates zero when not used for measurements. 2. switch, select the quantity to be measured, and the size (range selector switch knob): is the switch that users must choose whether to use a torque measuring instruments are all 4 volumes, each volume contains the measurement range to choose from. As follows:ACV: 0-10V, 0-50 V, 0-250 V and 1000 V-0 (includes 4 measuring range)DCV: 0-NN0D1 V 0-NN0D5 V 0-NN2D5, V, 0 V, 0-10 V, 0-250 V-50, and 0-1000 V (measurement range 7 total)DCA: 0-50A, 0-NN2D5 mA, 0-0, and 25mA-0.25 A (includes 4 measurement ranges)Resistance (): x 1 (read 0-2k)X 10 (read 0-20k)1k x (read 0-2000k, or 2 M)10k x (read 0-20 M) (including 4 measurement ranges)3. measuring slot anode (measuring terminal +)4. negative polarity gauge slot (measuring terminal-COM)5. measuring slot anode cases are measured audio frequency signal (output terminal)6. adjust button to zero ohms (0 adjust knob): used to adjust the needle point zero ohms when measuring both ends to tap before measuring resistance values for each measurement range.7. instrument panel (panel)8. needle pointer (pointer indicator)9. measuring (test lead): consists of 2 lines, red lines for anode and black for negative pole.10. the scale of measurement (reading scales): the measurement scale consists of 7 sorted from top to bottom, as follows (see also metric machine contains)
