METERING:
Kilovoltmeter: 4½ inch (11.4 cm) Taut-Band. 3 color-coded
scales: 0-7.5 kV (red), 0-15 kV (black) and 0-
1.5 reference (green). Accuracy: ±2% full
scale.
Megohmmeter: 4½ inch (11.4 cm) Taut-Band.
2 scales: 1-100 Megohms (red), 2-200
Megohms (black). Accuracy: ±2% of full
scale length at any marking, better near high
resistance end.
Ranges: 8 ranges, 4 per scale, as described in
following Table.
