4.6.2 Analog Input Configuration

Note.
The 'Analog I/P' tab is displayed only if 'Source ID' for the Recording Channel is set to an analog signal source – see
Section 4.6.1, page 72.
If an analog input is assigned to more than one recording channel, changes to any of its parameters and tags are applied to
each channel the input is assigned to.
If an analog input is already assigned to another channel, the edit keys (
•1 If this parameter is changed to or from 'Volt free digital input', internally recorded data files are recreated and unarchived data is
lost.
74
) are not available.
•1 Select the electrical characteristics of the input.
Note.
Simulated input types are available for evaluating
instrument features without the need for process
connections.
If 'Volt free digital input' is selected, the input channel
becomes a digital input channel – see Section 4.6.3,
page 77.
Select 'Off' to disable an analog input.
Warning.
Ensure that the appropriate electrical connections have
been made – see Section 5.4, page 100.
When 'Type' is set to 'Volts', input signals with voltages
greater than 2V (standard inputs) or 1V (high specification
inputs) be connected through an external voltage
must
divider (part no. GR2000/0375) – see Section 5.4.1,
page 100.
Input signals with voltages up to 2V (2000mV – standard
inputs) or 1V (1000mV – high specification inputs) may be
measured without the need for the voltage divider by
setting 'Type' to 'millivolts'.
An external 10Ω shunt resistor is required for current
ranges – see Section 5.4.1, page 100.
