*The interval between [ aOhs] and [ aOls] should be
with minimum over 50% of span; otherwise, it will
reflect the less resolution of analogue output.。
 Fine Zero & Span Adjustment for Analog Output
Setting Range: -38011~27524;
Users can get Fine Adjustment of analogue output
by front key on the meter. Please connect standard
meter to the terminals of analogue output for measuring
the output value. To press the front key(up or down key)
of meter for adjusting and checking the output.
● Fine Zero Adjustment for Analog Output) [aOzro]: ；
When the analog output and display the
correspondingminimum value (low) when there
is error, this parametercan be operated directly to
increase / decrease on theshift key or
up /
down keys to
make fine-tuning
● Fine Span Adjustment for Analog Output)
[ aOspn]: ；
When the analog output and display the
correspondingmaximum value (high value) when there
is error, thisparameter can be operated directly to
increase /decrease on the shift key or
up /
down keys to
make fine-tuning.
 High Limited for Analog Output) [aOlmt]
Setting Range: 0.00~110.00%;
User can set the output in high limit to avoid destroying
the receiver or protection system。

■ RS 485 Communication
CM1 series offers a Modbus RTU
mode protocol.Communication speed up to 38400
bps; users can useRS485 set parameters, read the
display.。
