I HIGH RESISTANCE indicator 9 blinking
There is a fault in the voltage circuit (E - S). At the start of the measurement, the instrument
automatically checks the resistance between E and S. If the resistance is higher than 50 kΩ,
the indicator 9 blinks, meaning your measurement may be impaired by the voltage circuit
resistance.
N.B: The indicator will blink during the whole measurement, even if the resistance comes
under 50 kΩ.
Check the rods, the leads and their connections.
I HIGH NOISE indicator 10 blinking
There are parasitic voltages in the voltage circuit (E - S), interfering with the measurement.
Move the rods.
