operation. The error messages and their description are listed below.
Setting Errors
Code Message Explanation/Countermeasures
1 System error. Contact your nearest YOKOGAWA dealer.
2 Incorrect date or time setting. Check the setting.
3 A disabled channel is selected. The channel does not exist.
4 Incorrect function parameter. Incorrect communication parameter.
5 The input numerical value exceeds the set range. –
6 Incorrect input character string. The entered character cannot be used.
7 Too many characters. –
8 Incorrect input mode. Incorrect range mode (Volt, TC, Scale, etc.) setting.
9 Incorrect input range code. Incorrect range type (2 V, R, PT100, etc.) setting.
10 Format error. Incorrect character string format.
11 Range settings are not same within the selected 
channels.
Channels whose range differs cannot be set simultaneously.
12 An invalid characters. Contains an invalid character.
13 Ref. CH error. Specify a channel whose range is set to voltage, TC, or RTD for 
the reference channel.
15 Too many characters for printout. Too many characters in the message printout including 
measured/computed values.
16 Too many characters for message. Cannot enter a setting that exceeds the message string (16 
characters).
21 Cannot set an alarm for a SKIPPED channel. –
22 The upper and lower span limits are equal. This is not allowed.
23 The upper and lower scale limits are equal. This is not allowed.
24 The lower span limit is greater than the upper span 
limit.
–
25 The lower scale limit is greater than the upper scale 
limit.
–
26 Bias cannot be set to the SKIPPED channel. –
27 Bias cannot be set to the DI channel. –
30 The partial boundary value exceeds the range of the 
span.
–
31 Partial is invalid on the SKIPPED channel. –
35 The upper and lower limits of the printing zone are 
equal.
Set the rightmost value of the zone – the leftmost value ≥ 5 mm. 
36 The lower limit of the printing zone is greater 
than the upper limit.
Set the rightmost value of the zone – the leftmost value ≥ 5 mm.
37 The printing zone is narrower than the minimum 
width (5 mm).
Set the rightmost value of the zone – the leftmost value ≥ 5 mm.
38 Partial is invalid on the DI channel. –
39 The bias and the calibration cannot be used 
simultaneously.
–
40 Datume value (1 >= 2) Set the correction point (measured value) of the first point less 
than that of the second point in the calibration correction.
41 Datume value (n-1 > n) Set the correction point (measured value) of the n–1
th
 point less 
than or equal to that of the n
th
 point in the calibration correction.
42 Revise value (n-1 >= n) Set the correction value of the n–1
th
 point less than that of the n
th
point in the calibration correction.
47 All items in DISP menu parameters are set to SKIP. –
48 Start = Finish.  The DST start time and end time cannot be set to the same time.
49 Invalid or missing DST time settings. Since the time gains one hour when the DST starts, the set-up 
time does not exist.
61 There is no channel specified by the MATH 
expression.
Set a computation channel.
62 MATH expression grammar is incorrect. Enter the equation correctly.
63 MATH expression sequence is incorrect. Enter the equation correctly.
