2. Switch to select the volume level will be measured and size (range selector switch knob): It is a switch, which requires the user to select whether to use Twist lung volume, which has a total volume of 4 each quantity range is selected, the measurement as follows:
ACV: 0 - 10 V, 0 - 50 V,0 - 250 V and 0 - 1000 V (as well as the range of measurement 4.)
DCV: 0 - 0.1 V, 0 - 0.5 V, 0 - 2.5 V, 0 - 10 V, 0 - 50 V, 0-0, 250 V - 1000 V (as well as the range of measure 7.)
DCA: 0 - 50 A, 0 - 2.5 mA, 0 - 25 mA, and 0- 0.25 A (as well as 4 during the measurement)
Resistance ( ): X 1 (read 0 - 2 k)
X 10 (read 0 - 20 k)
X 1K (read 0 - 2000 K or 2 M)
X 10K (read 0 - 20 M) (including the 4 temple)
3. The connector cable connector positive measure (measuring terminal)
