Alarm 1 to 4
Four alarms (Alarm 1 to 4) can be specified on each channel.
Type
Type Values Description
H An alarm occurs when the measured value exceeds the specified value.
L An alarm occurs when the measured value falls below the specified value.
h(dH)* An alarm occurs when the difference in the input values of two channels is
greater than or equal to the specified value.
l(dL)* An alarm occurs when the difference in the input values of two channels is
less than or equal to the specified value.
R(RH) The rate-of-change of the measured values is checked over a certain time
(interval). An alarm occurs if the rate-of-change of the measured value in the
rising direction is greater than or equal to the specified value.
r(RL) The rate-of-change of the measured values is checked over a certain time
(interval). An alarm occurs if the rate-of-change of the measured value in the
falling direction is greater than or equal to the specified value.
T** An alarm occurs when the measured value remains above the alarm value for
the specified time period.
t** An alarm occurs when the measured value remains below the alarm value for
a specified time period.
* Can be specified on channels set to delta computation.
** T and t can be selected when the alarm delay function is enabled in Basic Setting mode.
Alarm Value
Alarm is generated using the specified value as the boundary. The selectable range of
alarm values vary depending on the input mode and range.
Relay
To output relays, select the output relay number. Otherwise, select NONE.
Alarm Delay
An alarm occurs when the measured value remains above or below the alarm value for a
specified time period (alarm delay time).
Filter and Moving Average
Filter (Pen Model)
To use the input filter, select the time constant (2 s, 5 s, or 10 s).
Moving Average (Dot Model)
To use the moving average, select the sampling count (2 to 16).
Tag
Enter the tag using up to 7 characters. The characters that can be used are as follows (see
section 2.12):
Alphabet, numbers, symbols (%, #, °, @, +, –, *, /, (, ), µ, Ω,
2 , 3 , .), and space
Note
The setting of whether to use channel numbers or tags for printing is specified in Print Setting
under the Setup tab.
Zone
Sets the zone in which the measured values of each channel are recorded. Set the
position (mm) on the chart paper for the leftmost value of the recording zone (L) and
rightmost value of recording zone (R).
• Selectable range: 0 to 100 mm (µR10000), 0 to 180 mm (µR20000)
Set R to a value greater than L, and make the zone width (R – L) greater than or equal
to 5 mm.
