제 품 특 징
- Source: 4-20mA, 0-24mA with 1㎂ resolution(1KΩ load, 24V loop supply),
- Basic 정확도: 0.025%
- Source: 0-24.000V with 1 ㎷ resolution
- Source frequency 1~20000Hz square wave with programmable duty cycle (1~99%).
- Auto step and auto ramp for sourcing ㎃, V.
- Easy fixed 25% up and down, or programmable percentage (1-99%) increase and decrease (㎃, V)
- Measure DC ㎃ with loop power (24V output).
- Measure DC V.
- Measure Temperature (℃,℉) of 11 types of thermocouples (K,J,E,T,R,S,N,L,U,B and C).
- Calibrator grade precision temperature measurement with 0.1℃ & 0.1℉ resolution.
- Detection of thermocouples disconnection.
- Source and Measure at the same time.
- Warning for overload, output open (mA) or shor(V).
(과부하, 출력 개방 (mA) 또는 단락 (V)에 대한 경고)
- Short circuit protection for output.
- Battery power indication (%) when turn on the calibrator.
