Portacal 1000EU
Calibration device for current and voltage signals
The Portacal 1000EU is a calibration device which is
controlled by a microprocessor. It is used for current and
voltage signals. It has three output modes for simulating
signals:
• Voltage source: for the simulation of externally-supplied
voltage transmitters
• Current source: for the simulation of externally-supplied
current sensors
• Current sink mode: simulates the outputs of a two-wire
(loop-powered) transmitter.
Commonly used calibration functions can be invoked for
each mode by pressing a button. Up to 9 storage locations
per mode are available to save the individual values.
Furthermore, the Portacal 1000EU can be programmed
in a way that all modes can be cycled automatically. The
corresponding values are controlled continually for a pre-
dened time by means of a value storage. The following
values can be checked and parameterised:
• Voltage outputs
• Current outputs
• Two-wire transmitter outputs
The Portacal 1000EU provides the necessary voltage supply
for the sensor in order to check a two-wire transmitter.
Technical features:
• Complete diagnosis tool for current and voltage supply
• Measuring and simulating of voltage and current signals
• Simulation of function of signal transmitter, which can be
auxiliary-powered or process-powered (two-wire type)
• Continually adjustable step and ramping function
• Accuracy < 0.05 % in all signal domains
• Light and portable
• Supply via NiMH rechargeable battery or comparable
battery
• Signal tone at the press of a button
