1. Functions
■ 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
dened by the frequency mentioned above.
*1: The thermocouples comply with the Japanese Industrial Standard
JIS C1602 (ITS-90), except for the type-L and U thermocouples
that comply with DIN.
*2: The RTD comply with the Japanese Industrial Standard JIS C1604 (ITS-90).
The internal DIP switch can be congured so that the detectors comply with
IPTS-68 instead.
