SAR0101 AR-10
SAR0201 AR-7D
The optional
AR-10 or AR-7D
analogue signal
recording unit can be installed on the top cover
of the test equipment.
This facility can be used to monitor the
current/voltage outputs and binary input/output
status during the relay test process enabling
the fast trouble shooting of wiring and test
circuitry. We can also use this provision to
analyze the external signals, such as phase
angle, power, harmonic, etc.
