Loop calibrator PROVA-135

temperaturefrequencyfor electrical measuring instruments

• Source 4~20mA, 0~24mA with 1|jA resolution (1KQ load, 24V loop supply), basic accuracy 0.025%. • Source 0~24.000V with lmV resolution. Source frequency l~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 Température (°C, °F) of 11 types of thermocouples (K, J, E, T, R, S, N, L, U, B and C). • Calibrator grade précision température measurement with 0.1*C & 0.1*F resolution. • Détection 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. • Calibration of 4~20mA panel meters. • LED brightness testing (0~24mA). • Température calibration of panel meters or instruments for 11 types of thermocouples.
