Note 1: PT=Pt100 (IPTS-68: JIS'89), JPT=JPt100 (JIS'89), PT100-90=Pt100 (ITS-90: JIS'97),
PT50=Pt50 (JIS'81)
Note 2: Measurable data is within the range stated in the standard specifications.
Note 3: Burnout correction is the function of correcting an error caused by the burnout current
produced if an external conductor resistance is large.
Note 4: Up to 30 kΩ is possible, but the standard specifications indicate 100 to 2000 Ω in.
Note 5: Set in four significant digits or less. However, 10000 Hz can be set for span.
Note 6: Input zero adjustment and input span adjustment are to make input adjustments of each
direct input card. /A01, /A02, and /A03 enable the adjustment of the offset and gain of the A/
D converter. Select [INC] or [DEC] using the [ ] or [ ] software keys and press the [ENT]
software key twice to make an adjustment for each selection. Also, to reset adjustments
select [RST] and press the [ENT] software key twice. Zero and span are re-set in /A04. In
other words, making a zero adjustment with an input set to 0% and a span adjustment with
the input set to 100% (pressing the [ENT] software key twice) causes the zero (B10) and
span (B11) values to be re-set automatically.
Note 7: Output correction is for adjusting the D/A converter (1 to 5 V output) of each direct input
card. 0% output correction and 100% output correction enable offset and gain to be adjusted
respectively. Set a value in the range of ±10.00% and press the [ENT] software key twice.
This causes the D/A converter to enter a status in which the set value-added 0% output
value or the 100% output value is continuously output. To exit this status, display another
parameter once on the SC Setting Display, or turn the power supply OFF and then ON.
Note 8: If optional code /DF is specified, Fahrenheit tempertature range can be used for direct input
range in addition to centigrade temperature range.
Basic Operations
1) Erroneous setting prevention function
To prevent inadvertent operation, no parameter is selected (highlight displayed)
immediately after switching to the SC Setting Display. Press the [→] software key to
select parameter [SET] (parameter setting enable/disable) from the top line of the
display.
2) Setting-enable parameter operation
[SET] on the top line is the parameter for enabling SC maintenance communication.
This parameter is in [INHB] (setting inhibited) immediately after switching to the SC
Setting Display. SC maintenance communication cannot be accomplished unless this
parameter is set to [ENBL] (setting enabled). To do so, select the [SET] parameter
and then press the [ ] software key to change the setting from [INHB] to [ENBL]. At
the same time, [STOP] appears at the upper right of the display. Moreover, switching
to another display causes this parameter to return to [INHB] automatically.
3) Software keys
• [MNU] software key: Menu change key
Each time this key is pressed, YS1310 communicates with the SC to read out
and display the SC menus.
• [PRM] software key: Setting item change key
Each time this key is pressed, YS1310 communicates with the SC to read out
and display the SC setting items.
• [→] software key: Cursor movement key
When the data type is alphanumeric characters, this key moves an highlight
displayed digit to the right. In this case, should the highlight display be at the
rightmost digit, it then moves to the leftmost digit.
• [ ] software key: Data increase key
Increases data. Data changes cyclically.
• [ ] software key: Data decrease key
Decreases data. Data changes cyclically.
• [ENT] software key: Enter key
Writes data to the SC. Writing is done in the following two steps:
(1) Press the [ENT] software key. This causes the background color of all
communication data to be highlight displayed.
