1. If you wait more than 10 seconds

between the first measurement and the

second one, the instrument emits a

prolonged sound to signal the negative

outcome of the test and displays a screen

like this. It’s necessary to repeat the

entire procedure. Press GO and re-start

from point 6

2. If mode 1W is selected and the

instrument detects the connection of the

second probe like in mode 2W, a screen

like this is displayed to signal the error. A

prolonged sound is emitted until the error

condition is removed

3. If mode 2W is selected and the

instrument detects an input voltage

(between the two bushes) higher than

605V, a screen like this is displayed and

a prolonged sound is emitted until the

error condition is removed. Disconnect
