Digital display

Measured value or computed value

•DC voltage input: Displays values between “the min. measurable value – 5% of the span of the measurable range” and “the max. measurable value + 5% of the span of the measurable range” of the range (example: –2.200 to 2.200 V for the 2 V range).

•TC and RTD input: Displays values for input values between “the min. measurable value – 10°C”

and “the max. measurable value + 10°C” (example: –10.0°C to 1770.0°C for TC R)

•ON/OFF input (DI): Displays the input value 0 or 1.

•Linear scaling (1-5V, scaling, and square root): Displays value for input values between “the leftmost value of scale – 5% of scaling span” and “the rightmost value of scale + 5% of scaling span” (example: –5.0 to 105.0 when scaled to 0.000 to 100.0). However, the displayable range during scaling is from –19999 to 31500 (excluding the decimal). Values below –19999 and values above 31500 are displayed as –Over and +Over, respectively.

•Computation channel (/M1 option): Displays values in the range of –9999999 to 99999999.

Channel No.	Displayed with 1 character as follows:
	Measurement channels: 1, 2, 3, 4, 5, 6
	Computation channels: A, B, C, D, E, F, G, J, K, M, N, P
Alarm	Alarms are displayed using the symbols below. If multiple alarms are occurring simultaneously, the
	alarm with higher precedence is shown.
	(Higher precedence) H, L, T, t, h, l, R, r (Lower precedence)
Special values	Measurement channel
	Status	Display	Description
	+Over	+Over	See below.
	–Over	–Over	See below.
	Skip	SKIP	A value for channels set to skip.
	Error	ERROR	Values such as when both the reference channel and measurement
			channel are +Over or –Over in delta computation.
	+Burnout	B.out	A value displayed when a burnout is detected on a channel set to
			burnout up scale.
	–Burnout	B.out	A value displayed when a burnout is detected on a channel set to
			burnout down scale.

+Over and –Over of measurement channels

A condition in which the value is outside the display range indicated in “Measured value or computed value” above. For example,

•For 2 V range, values below –2.200 V are –Over and values over 2.200 V are +Over.

•For TC R, values below –10.0°C are –Over and values over 1770.0°C are +Over.

•If scaled to 0.0 to 100.0, values below –5.0 are –Over and values above 105.0 are +Over. However, the displayable range during scaling is from –19999 to 31500 (excluding the decimal). Values below –19999 and values above 31500 are displayed as –Over and +Over, respectively.

Computation channel

Status	Display	Description
+Over	+Over	When the computed result exceeds 99999999.
–Over	–Over	When the computed results is less than –9999999.
OFF	SKIP	A value for channels set to Off.

Channel switching interval The switching interval of displayed channels can be set to 1 s, 2 s, 3 s, 4 s, or 5 s.
