Furthermore the following messages can be displayed on the LCD screen

Message Advice
01 Out of range* Output is either above +1.0V or below
–1.0V.
Pressing AZERO may give an adequate read-out
again. If the message remains after pressing
AZERO, the autozero function is unable to com-
pensate the background cell current. Advice: use
a less sensitive range in the SETUP menu.
02 PAD overload Charging current in pulse mode out of range.
Pressing AZERO may give an adequate read-out
again. If not, it is advisable to change the pulse
settings (increase t1) or use a less sensitive
range.
Make sure that maintenance is performed on a regular basis.
*) An ‘Out of range’ error appears when the cell current I
cell
exceeds the
limit of the current range at which the measurement is performed. See fig-
ure below.
Fig. 59. Example of a current signal were the cell current exceeds the
maximum current level and the signal is ‘out of range’.
It is important to recognize an ‘out of range’ (overload) situation,
because it may lead to an incorrect assessment of the current during
an electrochemical reaction.
