Notes:
Input signal: BJ194L using a separate acquisition calculate for each measurement channel, to
ensure consistent in use, for different load forms, its a variety of connection mode. Access wire
shall be met: the current 2.5 square mm, voltage of 1.5 square millimeters.
A. Voltage input:
Input voltage should not exceed the rated input voltage products (100V or 400V),
Otherwise, you should use external CT. Suggest 1A fuse be installed in the voltage input side.
B. Current Input:
Standard input current is 5A, if greater than 5A should use external CT.
When the CT is connected with other instruments, make sure wiring methods be used in series.
Before remove the current input connection, must be sure to disconnect the primary circuit or
shorted secondary circuit of CT. In order to facilitate disassembly, please do not connect to CT
directly, and the terminal block is suggested.
C. Please make sure that the input voltage and current corresponding to the same phase
sequence, and the same direction; Otherwise, the Values and symbols will be wrong!!
(Power and Energy)
The input network configuration of instrument depends on the CT number of the system:
in the condition of 2 CT, select the three-phase, three-lines two components;
in the condition of 3 CT, select the three-phase, four-lines three component mode.
Instrument connection mode, set of the instrument (programming input network NET)
should be the same load wiring as measured wiring. Otherwise, the measurement instrument
will lead to incorrect voltage or power.
In three-phase three-wire mode, the measurement and shows the line voltage;
In three-phase four-wire mode, the measurement and shows the phase voltage.
Auxiliary power
:
BJ194L series mini multi-function meter with universal (AC / DC) power input, if not for a
special statement, we provide the 220VAC/DC or 110VAC/DC power interface for standard
products. Instruments limit work power supply: AC / DC: 80-270V, please ensure that the
auxiliary power can match with BJ194Z series meter to prevent damage to the product.
A. Suggest install 1A fuse in the fire line side.
B. For the areas with poor power quality, suggest install lightning surge suppressor and rapid
burst suppressor to prevent lightning strikes.
