3.3.1.4. CURRENT LOOP ANALOG OUTPUTS (OPTION 41) SETUP
Servicing or handling of circuit components requires electrostatic discharge
protection, i.e. ESD grounding straps, mats and containers. Failure to use ESD
protection when working with electronic assemblies will void the instrument
warranty. For information on preventing ESD damage, refer to the manual,
Fundamentals of ESD, PN 04786, which can be downloaded from our website at
http://www.teledyne-api.com

TEST CHANNEL
To change the settings for the analog output channels, see Section 5.9.2.
If your analyzer had this option installed at the factory, there are no further connectons
to be made. Otherwise, it can be installed as a retrofit for each of the analog outputs.
This option converts the DC voltage analog output to a current signal with 0-20 mA
output current, which can be scaled to any set of limits within that 0-20 mA range.
However, most current loop applications call for either 2-20 mA or 4-20 mA range. All
current loop outputs have a +5% over-range. Ranges with the lower limit set to more
than 1 mA (e.g., 2-20 or 4-20 mA) also have a -5% under-range.
Figure 3-9 provides installation instructions and illustrates a sample configuration of one
current output combined with two voltage outputs . Next are instructions for converting
current loop analog outputs to standard 0-to-5 VDC outputs. To calibrate or adjust these
outputs see Section 5.9.3.7.
