Fluke 79 acting up
You should check its battery, that's where your problem is. Electronic
meters utilize A/D converter, the converter uses Voltage reference, when
battery is weak it give faulty voltage reference, as a result you get
faulty reading. Do not rely on voltage reading, sufficient voltages do
not
mean sufficient Battery without enough current in battery.
I put a brand new battery in it, the symptoms are unchanged.
