1.
To inspect whether did the input
signal type (V/A/mA..) of meter
match with field signal or not?
Please change another meter that is matching in the field.
►For CS2-PR, input range can be programmed in same
type(mA or V). Please check the
[
aItyp
]
in
[
input group
].
2.
To inspect whether the input signal
is over +120% (input high limit) or
-120% (input low limit)?
A.
Please check the
[
aIlo
]
and
[
aIhi
]
in
[
input group
]
are
correct or not.
B.
Please changes another meter that is matching in the field.
3.
To inspect whether did the wires
connect correct and secure or not?
A.
Please checks carefully the connection diagram of label on
the meter.
B.
Please uses the terminals(Y, Ring or cord end terminal) to
avoid the risk of insecure.

1.
To inspect the input signal type
(V/A/mA..) or range of meter
whether did match with signal in
the field or not?
A.
Please check the
[
aIlo
]
and
[
aIhi
]
in the
[
input group
]
whether did the both set correct or not ? Generally, the
[
aIlo
]
is
)00
%
and
[
aIhi
]
is
10)00
%
, if the input
specification of meter is same as range of signal in field.
B.
Please changes another meter that is matching in field.
2.
To inspect the settings of high and
low scale whether did it correct or
not?
Please check the
[
hIsc
]
(A-05)
and
[
lOsc
]
(A-04)
in
[
input
group
]
.
3.
To inspect the high and low fine
adjustments of PV are changed or
not?
Please check the
[
pVspn
]
(A-07)
and
[
pVzro
]
(A-06)
in
[
input
group
]
whether did the values can be cleared in
[
ZSclr
]
(A-08)
.
CS2-Pr:
4.
To inspect the input signal range
whether did it match with signal in
the field or not?
Please check the
[
aItyp
]
(A-00)
that has to match the signal in
the field.
CS2-SG/CS2-PM
5.
To inspect the field calibration
whether did it match with sensor in
the field or not?
Please check the
[
caLls
]
(F-02)
and
[
caLhs
]
(F-04)
both are
matched the measuring range of sensor.
Jittery Display 1.
To inspect the input signal is jittery
or not?
A.
If the input signal is jittery continuously, please set higher
value in
[
avg
]
(A-11)
or
[
mVavg
]
(A-12)
B.
If the input signal is jittery uncertain period that caused by the
inductive load actions, please set higher value in
[
Dfilt
]
(A-13)
C.
Please does not lay the wires of input together with
high-voltage lines or power lines. As a general rule, wire the
meter in a separate system, use an independent metal
conduit, or use shielded cable.
2.
To inspect the input signal is
stable.
A.
If the input signal is jittery continuously, please set higher
value in
[
avg
]
(A-11)
or
[
mVavg
]
(A-12)
B.
If the input signal is jittery uncertain period that caused by the
inductive load actions, please set higher value in
[
Dfilt
]
(A-13)
C.
Please connects an isolation transformer as close as meter
in power lines.
