■ Main Functions
• Source
The calibrator sources a voltage, current, resistance, thermocouple
(TC), RTD, frequency or pulse signal at a preset level.
Function
Description
DC voltage
Sources a DC voltage signal in the 100 mV, 1 V, 10 V or
30 V range.
DC current
Sources a DC current signal in the 20 mA range.
SINK current
Draws a sink current from an external power source in
the 20 mA range.
Resistance
Sources a resistance signal in the 400 Ω range.
Thermocouple (TC) Sources a thermoelectromotive force corresponding to
the temperature detected by a type-K, E, J, T, R, B, S, N, L
or U thermocouple.
*1
RTD
Sources resistance corresponding to the temperature
detected by a Pt100 or JPt100 RTD.
*2
Frequency and
pulse
Sources a continuous pulse train with frequency in
the 500 Hz, 1 kHz or 10 kHz range.
This function also sources the preset number of pulses
defined by the frequency mentioned above.
*1: The thermocouples comply with the Japanese Industrial Standard
JIS C1602-1995 (ITS-90), except for the type-L and U thermocouples
that comply with DIN 43710-1985.
*2: The RTD comply with the Japanese Industrial Standard JIS C1604 (ITS-90).
(Pt100: JIS C 1604-1997, JPt100: JIS C 1604-1989)
The internal DIP switch can be configured so that the detectors comply with
IPTS-68 instead.
