Dc Voltage Measurements - Sealey TA320 User Manual

Operating Instructions
WARNING: Risk of electrocution. High-voltage circuits, both AC and
DC, are very dangerous and should be measured with great care.
1. ALWAYS turn the function switch to the OFF position when the
meter is not in use.
2. If "OL" appears in the display during a measurement, the value
exceeds the range you have selected. Change to a higher range.
