The instrument can displays messages when pressing the F1 key:
Message Description
Before start a test, please check
zero reading of DC clamp when
it’s not connected to the plant
ALWAYS perform at the start of each test the zeroing of the supplied DC clamp connected to
the meter and not to the PV installation by pressing ZERO key on it. The result should be a
“0.000A” on meter but a small current value up to “0.02A” is permitted. After that, connect the
DC clamp to the installation
Fw SOLAR-01 < 2.02 – Irr.min =
600W/m2
The minimum irradiance threshold different from 600W/m
2
and the internal Fw of SOLAR-01
is < 2.02. The Fw update of SOLAR-01 unit require to send the unit to HT service
Fw SOLAR-01 < 2.03 – IP=2min
The IP > 2min and the internal Fw of SOLAR-01 is < 2.03. In this case the recording is
aborted as the not updated SOLAR-01 can not saving the values in it’s internal memory. The
Fw update of SOLAR-01 unit require to send the unit to HT service
No supply
It is recommended to connect the supply provided with the instrument, before starting
testing/recording. Anyway, it is also possible to perform a testing/recording without supply,
using the instrument’s internal battery.
Wrong phase sequence
The value of parameter “ SEQ ” in section Measure display (see § 5.2.4)is different from “ 123 ”,
which is correct. Check the sequence value of the phases of Voltages V1, V2, V3.
Negative powers
One or more values of the Active Powers P1, P2, P3 are negative (see § 5.2.4). If necessary,
turn the clamps under current by 180° on the conductors in order to obtain always positive
values (except for cases of co-generation).
Solar 01 connected
Solar 02 connected
Confirms the connection between the instrument and SOLAR-0x. This message MUST
ALWAYS appear when connecting the instrument and SOLAR-0x using the USB cable.
Should this message not appear when connecting, disconnect and connect again the USB
cable to the two units.
SOLAR-01 not connected
SOLAR-02 not connected
Check the connection of SOLAR-0x to the instrument. The error message is displayed when
trying to stop a testing or trying to start/stop recording where item SOLAR-0x is flagged,
while no connection to unit SOLAR-0x has been detected.
SOLAR-0x is not recording. Stop
recording.
This message warns the user that a SOLAR-0x unit with no active recording has been
connected to a instrument unit during the testing/recording phase.
Testing in progress
This message is displayed when a testing is being carried out and the GO/STOP key is
pressed. It is not possible to start recording while a test is already being carried out. Stop
testing by pressing the F1 key (FINISH).
Do you want to stop recording?
Message which asks the user for confirmation before stopping the recording/test currently
being carried out.
Wait for recording start
This message warns the user that the recording/test will start when reaching the following
minute or when reaching the date and time set for start (only for recordings on NPV
systems).
Wait for data download
This message warns the user of the data transferring phase from unit SOLAR-0x to the
instrument. Do not disconnect the USB cable during this phase.
Analysis impossible
This message warns the user that the data recorded are not compatible with the set
minimum irradiation threshold (see § 5.3.3.3) and it is not possible to provide any result.
MPP300 connected
This message confirms the connection between the instrument and MPP300. This message
MUST ALWAYS be displayed when connecting the master unit to the MPP300 via USB
cable. If, upon connection, this message should not appear, disconnect the USB cable and
connect it again.
Error in data download from
SOLAR-02
A transmission error has occurred between the SOLAR-02 and SOLAR300N or MPP300
units. Switch off and on again all units and connect them again. The units will try data
transfer again.
MPP300: low battery
The battery of MPP300 is almost flat. Connect the external power supply to MPP300.
No external power supply for
MPP300. Continue?
This message warns that, in order to carry out very long recordings, it is advisable to connect
the external power supply to MPP300.
MPP300: exchanged AC and DC
voltages
An exchange in the connection between DC and AC voltages has been detected. Check the
connections.
MPP300: negative power One or more Ac negative powers has been measured. This is normally due to a connection
error. Check the connections.
SOLAR-02: not detected. Stop
recording?
You are trying to stop recording while the SOLAR-02 unit is not connected with the MPP300
unit.
SOLAR-02:Firmware not correct Firmware of SOLAR-02 dosen’t match with SOLAR300N Firmware
MPP300:Firmware not correct Firmware of MPP300 dosen’t match with SOLAR300N Firmware
