Tone generator and pickup
APPLICATION.
The Z200 is capable of transmitting frequencies that
may be picked up and heard as ”beep” sounds using a
handheld pickup. Such testing allows to determine what
string the instrument is connected to, in cases where
the mapping of a solar PV system is less than optimal or
simply in cases where the system is build by many strings.
Disconnections may also be found using the pickup.
Simply start the ”Tone generator” and use the pickup to
detect the transmitted frequencies.
This mode sends out a medium fre-
quency tone between positive and
negative terminals.
This mode alternates between
high and low frequency between
ground and positive, and between
ground and negative.
NOTICE.
Important information.
If only a partial disconnect
exists in the string, it may be difficult to identify the exact
position with this method, as the difference in the tones
heard will be smaller and smaller the better the remaining
connection is.
