Scan Interval
For conguration instructions, see section 3.1.
• A/DConverterIntegration Time
The MV uses an A/D converter to convert sampled analog signals to digital signals.
You can effectively eliminate the inuence of power supply noise by setting the A/
D converter’s integration time to the same length as or to an integral multiple of the
power source period.
• Because 100 ms is an integral multiple of both 16.7 ms and 20 ms, you can effectively
eliminate the influence of power supply noise from both 50- and 60-Hz frequencies by
setting the integration time to 100 ms.
• Power supply noise elimination is less effective in fast sampling mode than it is in normal
mode. When measuring in an environment susceptible to power supply noise, we
recommend that you measure in normal mode.
For conguration instructions, see section 3.1.
Input Types and Computation Functions
You can measure the following types of input.
Input Type Description
DC voltage You can measure DC voltages in the range of ±20 mV to ±50 V.
M-4660
DC current You can measure a DC current signal by converting it to a voltage signal using a shunt
resistor attached to the input terminal.
The converted signal can be measured within the DC voltage range (see above).
Thermocouple You can measure temperatures using these thermocouple types: R, S, B, K, E, J, T, N,
W, L, U, and WRe3-25. It is also possible to measure using other thermocouples, such as
PR40-20 and PLATINEL.
RTD You can measure temperatures using RTD types Pt100 and JPt100. It is also possible to
measure using other RTD types such as Cu10 and Cu25,3 and Pt50 and Ni100.
ON/OFF input You can display contact input or voltage input signals correlated to 0% or 100% of the
display range.
Contact input: A closed contact is ON (1). An open contact is OFF (0).
Voltage input: Less than 2.4 V is OFF (0). 2.4 V or more is ON (1).
Pulse input
1 Shunt resistor sold separately. For example, you can use a 250-Ω shunt resistor to convert a 4- to 20-mA
signal to a 1- to 5-V signal.

1.2 Input
Feature Overview
Note
You can use difference computation even if the reference channel and difference computation
channel’s input types and ranges are different. Difference computation takes place using the
difference computation channel’s decimal place and unit.
Example 1: If the input value of the difference computation channel is 10.00 and the measured
value of the reference channel is 100.0, the result is 10.00–100.0=–90.00.
Example 2: If the input value of the difference computation channel is 10.00 V and the
measured value of the reference channel is 5.00 mV, the computed result is 10.00
V – 5.00 mV = 5.00 V.

Alarm Types
This function generates an alarm when the measured data meets a set condition. You
can set a maximum of four different alarms on each channel.
You can use the types of alarms listed below. The letters contained in parentheses are
used as abbreviations for the alarms.
For alarm conguration instructions, see section 3.7.
• Hysteresis
You can set a difference between the value that activates an alarm and the value that
deactivates it.
For conguration instructions, see section 3.5.
• Delay High Limit Alarm and Delay Low Limit Alarm
If the measured value remains above or below the set alarm value for the set period of
time (the delay time), an alarm is activated.
• High Limit on Rate-of-Change Alarm and Low Limit on Rate-of-Change
1-6
Alarm
The MV checks the rate-of-change of the measured values over a set period of time (the
interval) and activates an alarm if the rate-of-change in the rising or falling direction is
greater than or equal to the set value.
The alarm value of the rate-of-change alarm is set using an absolute value. The
interval is derived from the sampling count using the following equation:
Interval = scan interval × sampling count
For instructions on how to set the interval, see section 3.5.
• Difference High Limit Alarm and Difference Low Limit Alarm
The MV activates an alarm when the difference between the values of two channels
goes above or below the set value. You can use this alarm on measurement channels
set to difference computation.

Note
When reflash is enabled, the first three output relays are used exclusively as reflash relays.
The first three output relays are set to OR logic and to the Nonhold operation regardless of the
AND/OR or Nonhold/Hold settings explained below.
• AND/OR
When multiple alarms are assigned to one output relay, you can choose to activate the
alarm in one of the following ways (you can also use AND/OR with internal switches):
• AND: Activate the relay when all of the alarms assigned to it occur simultaneously.
• OR: Activate the relay when any of the alarms assigned to it occur.
• EnergizeorDe-energizeOperation
You can choose whether to energize or de-energize alarm output relays when an
alarm occurs. If you select de-energize, the alarm output relays will be in the same
state when the power is shut off as they are when an alarm occurs. This setting
applies to all alarm output relays.
Internal Switch
• Nonhold/Hold
When an alarm condition is no longer met, alarm relays can be set to:
• Turn OFF immediately (Nonhold).
• Remain ON until the execution of an alarm output release (AlarmACK) operation (Hold).
This setting applies to all alarm output relays.
• Alarm Output Release Operation
The alarm output release operation (AlarmACK) stops the display and the relay output
of all alarms. For information about how alarm display and output relay operations
respond to an AlarmACK operation, see the previous page.
Note
When you enter Basic Setting Mode, the alarm output relay remains at its current active/
released state. In Basic Setting Mode, alarms are not detected and the AlarmACK operation is
invalid.
The MV can transmit the alarm status to software switches (30 internal switches).
Internal switch values are shown below. As with AlarmACK, you can apply an AND or OR
operation (see the previous page).
1-8
Internal switches can be used as events with the event action function (for details, see
section 1.7). Internal switches can also be written into computation channel (/M1 and /
PM1 options) expressions.

• Waveform Updating
Every 30 dots makes up one division (also referred to as DIV) on the time axis.
The waveform update interval is the time corresponding to one dot. The time
corresponding to one dot depends on the time set to one division (the trend interval).
The relationship between the trend update interval and the speed of waveform
movement in the display is as follows:
Trend interval (per DIV) 5 s
Time corresponding to one dot (in seconds) 0.125 0.25 0.5 1 2
Speed of waveform movement (approximation in mm/h) 10000 5000 2500 1250 625
Trend interval (per DIV) 2 min 5 min 10 min 15 min 20 min
Time corresponding to one dot (in seconds) 4 10 20 30 40

Digital Display
Displays measured data using large numeric symbols.
For operating instructions, see section 5.2.
Note
• MeasurementChannelNumeric Value Display
When the MV detects a range-out (see below), the display is either “+Over” or “-Over.”
When the MV detects a burnout on a channel that has been set to be checked for burnouts,
the display is “Burnout”. All other values are displayed numerically.
Range-outs are detected on measurement channels in the following circumstances.
• If the DC voltage input value goes above the measurable range ± 5%, a range-out is
detected. For example, when the measurement range is 2 V, the measurable range is
–2.000 to 2.000 V. If the voltage exceeds 2.200 V, a positive range-out is detected. If it
goes below –2.200 V, a negative range-out is detected.
• If the input type is thermocouple or RTD, a range-out is detected when the temperature
goes 10°C above or below the measurable range. For example, when the measurement
range is set to R, the measurable range is 0.0 to 1760.0°C. If the temperature exceeds
1770.0°C, “+Over” will be displayed. If the temperature goes below -10.0°C, “-Over” will
be displayed.
• On channels that use linear scaling, the range-out values, ignoring the decimal point,
are above 30000 and below –30000. However, you can also set the range-out values to
105% or greater, and –5% or less of the scale width, as long as those values fall within
±30000.
For configuration instructions, see section 3.11.
• ComputationChannelNumericValueDisplay
See section 1.9.
• ExternalInputChannelNumericValueDisplay(/MC1option)
The range of displayable values, ignoring the decimal point, is –30000 to 30000. The
decimal place is determined by the location of the decimal point on the external input
channel’s minimum span value. Regardless of maximum and minimum span value settings,
all values within the range of –30000 to 30000 will be displayed. If the value exceeds 30000,
“+Over” will be displayed. If the value goes below –30000, “-Over” will be displayed.
