4.6.2 Analog Input Configuration

Notes.
• 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.
• 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 (
Analog I/P A1
Type milliamps
•1 If this parameter is changed to or from 'Volt free digital input', a new internal data file for this recording channel is created. All
historical data stored internally for this channel is lost.

) are not available.
Select the electrical characteristics of the input.

Notes.
• 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.
• Select 'Off' to disable an analog input.
Warnings.
• Ensure that the appropriate electrical connections have
been made – see Section 5.4.
• When 'Type' is set to 'Volts', input signals with
voltages greater than 2V
an external voltage divider (part no. GR2000/0375) –
see Section 5.4.1.
• Input signals with voltages up to 2V (2000mV) 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.
