Functions
• Generation Functions
A specified value (in five digits) in function units of voltage, current, resistance,
thermocouple, resistance temperature detector (RTD), frequency, or pulse signal can
be generated.
Function
Description
DC voltage
Available in three ranges: 100 mV, 1 V, or 10 V
Direct current
Available in 20-mA range. SINK function is also available.
Resistance
Available in 3 ranges: 500
Ω
, 5 k
Ω
, or 50 k
Ω
Thermocouple
Thermoelectromotive force can be generated according to the
temperature of type K, E, J, T, N, R or B thermocouple.
Resistance temperature detector
A resistance can be generated according to the temperature of PT100
resistance temperature detector.
Frequency and pulse signal
Frequency is in four ranges: 100 Hz, 1000 Hz, 10 kHz, or 50 kHz.
Voltage is in the same range as the 10 V range for voltage generation.
Pulse signals with a specified number of bursts (1 to 60000) are
available as well as the above.
• Measurement Function
Voltage, current, or resistance can be measured and displayed in 4.5 digits
independent of the generation function.
Function
Description
DC voltage
Available in three ranges: 500 mV, 5 V, 35 V
Direct current
Available in two ranges: 20 mA, 100 mA. An overrange input protection
fuse comes built into the current-input terminal.
Resistance
Available in three ranges: 500
