Q&A
Question
What types of Interface Unit can be used?
Why does an error occur and settings cannot be made
when teaching or directly inputting threshold values?
When scaling is executed, an error appears on the
sub-display and settings cannot be made.
When monitor focus is executed, why does an error
appear on the sub-display and the settings cannot be
made?
Can calculations be performed with three or more
Amplifier Units?
Can calculations be performed when Sensor Heads
with different measuring ranges are connected to two
Amplifier Units?
How many Amplifier Units can be connected and
communicated with the Interface Unit?
Is warm-up operation still required even if bank shift
input is cancelled?
Answer
A ZJ-SF11 is required.
A ZX-SF11 compatible with the ZX series cannot be used.
Threshold values cannot be set using teaching or by direct
input if the following condition is not met:
• HIGH threshold - LOW threshold value > hysteresis width
p.64
Scaling cannot be set for one of the following reasons:
• Scaling has been attempted when the measured value is
outside the measuring range.
• When two-point scaling has been executed, the distance
between the measured values for the two points is not at
least 1 kV of the rated measuring range.
p.99
Monitor focus settings cannot be made when the distance
between the two specified points is not at least 1% of the
rated measuring range.
p.70
The ZJ-SD does not have a function for calculating
measurement results.
The ZJ-SD does not have a function for calculating
measurement results.
Up to five Amplifier Units can be connected to the ZJ-
SDA11.
No, it is not.
