To set the range back to H, press the SHIFT + R SET (RANGE) key to
change the range indicator to H.
The resistance limit value changes from the previous L range limit value (9.000 0
Ω
) to
the next highest H range resistance setting (9.009 0
Ω
).
• Setting range for H range: 1
Ω
to 1 k
Ω
Setting range for L range: 10
Ω
to 10 k
Ω
Although the setting range specifications are as listed above, the L range actually
permits settings from 9.000 0
Ω
to 10.000 k
Ω
.
Accordingly, in the example in step 8, the minimum value when changing to the
L range is 9.000 0
Ω
and the range in which the H and L ranges overlap is 9.000 0
Ω to 1 000.0 Ω .
• The setting resolution and operating range for the L range is one tenth of the H
range in units of siemens.
• The units for the setting resolution of the resistance limit value is S (siemens).
Accordingly, you may sometimes not be able to set your desired resistance limit.
In this case, the PCZ1000A is set the next highest resistance value allowed by
the resolution.
For example, if operating in the H range by remote control, sending a setting
input of 251
Ω
(3.98 mS) will result in an actual setting of 333.33
Ω
(3 mS).
• If the resistance limit setting is such that the current is close to 0 A (for example,
if the resistance limit is set to 10 k
Ω
for a 10 V input), an offset current of several
tens of mA may flow. (The setting accuracy of the PCZ1000A is ± (2 % + 0.2
A).)
• The actual resolution at close to 0 A may be degraded due to this offset current.
(The setting resolution is the minimum possible change in setting value.)
