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

Current "SINK"
Description
It is possible to set current of ± 200 nA ... ± 52 mA, voltage of
± 1 µV ... ± 30 V and, optionally, temperature setpoint value of
14 thermocouples types.
The output value is fed back via the sense 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.

with constant delta values and delta time
► Ramp 2
with variable delta values and internal time.
The ramp function allows single or repeated outputs in sawtooth or triangular form. The
number of steps can set from 0 to 99 (0 is continuos). The START, END and DELTA values
can be entered in µV, mV, V, mA and temperature values. DELTA time is displayed as

Optionally the thermocouples types R,
S, B, J ,T, E, K, U, L, N, M, C, D and
G2 can be simulated. For the "manual"
reference junction at 0 °C the accuracy
depends on the thermocouples model
starting at 0.1 K.
The connection occurs direct at the
standard terminals or "externally" via
an external, attachable reference junction model 4485-V001, at which the
temperature is detected with a Pt100
sensor (see application 1)

Application Example
1. Calibration of a PC card with a thermocouple measurement input
Instead of the thermocouple the calibration source DIGISTANT® model 4462 is connected. Using an external DKD-calibrated reference junction the PC card is retraceable calibrated with the optimum accuracy. Up to 14 thermocouples can be selected.
