| Safety Voltage Check |
Voltage measurement: 0.1 V - 600 V a.c; the meter is RMS calibrated and average responding
Safety voltage indicator: Indicates the presence of d.c. voltages.
Scaling is not the same as the a.c. meter. True d.c. voltage equals
scale reading divided by 2.22
Accuracy: 2.5% of full scale |
| Power Supplies |
MJ159 and MJ160: Low voltage brushless a.c. generator. Cranking speed between 130 rpm and 170 rpm
MJ359: Dual operation low voltage brushless a.c. generator or 120
V 50/60 Hz mains (line) supply
MJ459: Six IEC LR6 cells (AA) Battery life: not less than 1300
insulation or Resistance range tests
