The precision
calibration unit combines high accuracy,
low drift, low noise and superior
long-term stability with multiple
functionality and simple operation.
Ramps, delta + / delta -, and multiple
setpoint storage make the operation of
the device easier for the user.
For that reason the application
possibilities are many:
 |
Testing current and
voltage meters |
|
Precise testing of
thermocouple temperature
measuring instruments |
|
Calibration of
controllers, sensors, detection
devices and other devices used in
process control |
|
Open-loop process
control with the aid of
integrated ramp functions. |
The
DIGISTANT ® type 4462 can be used both
as a stand-alone table-top device, as
well as in automatic, computer-assisted
manufacturing and testing systems.

| Description |
 |
It is possible to
set currents of ± 200 nA ... ± 52 mA, voltages of ± 1µV ... ± 30 V and,
optionally, temperature setpoint values
of 14 thermocouple types.
The
output value is fed back via the sensor
line to eliminate voltage drops across
the measuring leads.
The device
has an adjustable current/voltage
limitation. An external voltage divider
of 1 up to 1:1000 can be considered
internally.
With the thermovoltage sourcing option
you can enter °C, °F and K, the
temperature scales ITS 90 or IPTS 68 and
the comparison point mode
constant/external. Furthermore, when
sourcing thermocouples a calibrated
external comparison point can be used,
whereby the data for calibration in the
device can be taken into consideration.
Indication of the source value is
carried out in large 12 mm figures on an
illuminated graphics-LCD.
The device can be operated both via
the keyboard as well as the interface.
