4-20mA Loop Calibrator + Thermometer
- Source 4~20mA, 0~24mA with 1μA resolution (1KΩ load, 24V loop supply), basic accuracy 0.025%.
- Source 0~24.000V with 1mV resolution.
- Source frequency 1~20000Hz square wave with programmable duty cycle (1~99%).
- Auto step and auto ramp for sourcing mA, V.
- Easy fixed 25% up and down, or programmable percentage (1~99%) increase and decrease (mA, V).
- Measure DC mA with loop power (24V output).
- Measure DC V.
- Measure Temperature (°C, °F) 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*C & 0.1*F resolution.
- Detection of thermocouples disconnection.
- Source and Measure at the same time.
- Warning for overload, output open (mA) or short (V).
- Short circuit protection for output.
- Battery power indication (%) when turn on the calibrator. Applications:
- Calibration of 4~20mA panel meters.
- LED brightness testing (0~24mA).
- Temperature calibration of panel meters or instruments for 11 types of thermocouples.
