Multifunction Calibrator
The memocal certo (Documenting Process Calibrator) is a hand tool for calibration
maintenance and trouble shooting of virtually all the control process instrumentation.
The memocal certo series features:
Transmitter simulation program
· Calibrate temperature, pressure, current dc, voltage dc, frequency
The instrument can be used as a temporary signal converter
replacement. Any input signal (electric or pressure) can be converted
into a 4-20 mA output.
The galvanic insulation between the input and output channels allow
also to use of this feature on the process.

Programmable generator
Task
The memocal certo can store and recall up to 10 complete
instrument configurations. By pressing 2 keys only you can store or
recall the configuration of both the channels and the display
(including input and output values too). In this way the work on field
is simpler and quicker.
· Autoramp and Autostep capability with Start, End, and Step
programmable parameters
· Single and continuous cycle with Start, End, Rises, Soaks, and
Falls programmable parameters
· the signal value setting
uses a unique in-line
single-digit setting mode
or a direct numeric entry
· direct keypad access to
n.10 programmable
memory stored values

Built-in calculator
A special calculator function is integrated in memocal certo. You can
read the value from the input channel, operate on it, and then write
the result on the output channel. All standard math functions are
included.
Multichannel Data logging
The calibrator can be used as a multichannel datalogger for
electrical and temperature signals. The graphic mode allows you to
display the trend; the Replay function allows you to generate the
electrical signal using the data stored. The DataCal PC software
allows the data storage in the hard-disk.
Transmitter Calibration
The memocal certo can be configured to easily manage the check
and the calibration of any pressure and temperature transmitter. The
wide display lets you simultaneously display the input and output
values and to select the right units for the transmitter under test.
The current or voltage reading can be scaled/converted in % of span
or in the engenieristic unit to simplify the verification operations. The
measuring circuit is also able to power the loop for a direct
connection with the transmitter under test.
All the memocal certo capabilities let the calibrator useful for all the
checks and calibration activities.
Software
Switch Test
Temperature and signal switches can be tested using this advanced
procedure. The calibrator will hold the display reading when the
contact changes status.
Our software has been designed to be used in industries, where
there are both laboratory and maintenance on field needs. It is a
WindowsTM software designed to plan, manage and document all the
calibrations and the certifications of the process instrumentation.
