Number of Measurement Channels and Scan Interval
The recorder samples the input signals on the measurement channels at the scan
interval to obtain the measured values.
Model Number of Channels Scan Interval
1-pen model 1
2-pen model 2
3-pen model 3
4-pen model 4
Dot model 6
Input Type, Measurable Range, and Computation
The recorder can measure the following types of inputs.
Input Type Measurable Range
DC voltage DC voltage in the range of ±20 mV to ±50 V
1-5V See "1-5V" below.
Thermocouple Temperature range corresponding to each type: R, S, B, K, E, J, T, N, W, L, U, and
WRe
RTD Temperature range corresponding to each type: Pt100Ω and JPt100Ω
ON/OFF input Contact input: Open contact is OFF (0). Closed contact is ON (1).
Voltage input: Less than 2.4 V is OFF (0). Greater than or equal to 2.4 V is ON (1).
Within ±6 V.
• 1-5V
1-5V is scaled to values in the appropriate unit to be used as measured values. Also,
the low-cut function (input less than 0% is fixed to 0% (scale left value)) can be used.
• Current Input
A shunt resistor is attached to the input terminal. The current signal is converted to a
voltage signal and measured. The measurable range is the range equivalent to the "DC
voltage" range indicated above after converting the current to the voltage signal.
Note
Three types of shunt resistors (250 Ω, 100 Ω, and 10 Ω) are available for current input (see
"Optional Accessories (Sold Separately)" on page vii). For example, a 250-Ω shunt resistor is
used to convert the signal to the range of 1 to 5 V for 4 to 20 mA input.
• Range Type, Measurable Range, and Recording Span
Various "range type" are available for the different types of inputs (for example
thermocouple type R). Each range type has a preset measurable range (0.0 to
1760.0°C for thermocouple type R). Measurement can be made by specifying an
arbitrary range within the measurable range as the input range. The measured values
in the input range are recorded on the chart paper. The range of measured values that
are recorded is called the recording span.
