3.5.2 Standard Analog Output
The PanaFlow Z3 has one Analog Output and one Digital Output in Standard configuration.
3.5.2.1 Setting up Analog Output
The PanaFlow Z3 meter has one Analog Output in standard configuration. For additional Analog outputs Optional I/O
boards may be purchased. Use steps as in section “Log-in and Primary Pages” to navigate to the
Input/Output
settings page.
1. Select [Analog Output (Std)] and press [ENTER] .
2. If you do not wish to connect an Analog Output, you should turn Analog Output selection to OFF.
3. If you are connecting an Analog Output, choose 4-20mA option. The Figure 23 below, shows the available
options.
4. Select the Measurement to be sent out on the 4-20mA output, followed by the [Base Value] and [Full Value]
selection. Refer Table 2 to see measurement options available for Analog output.
5. Select [Error Handling] . Refer to Section 3.5.2.2 to choose an option that suits your needs.
3.5.2.2 Understanding the Error Handling Option
The following Table 3 shows the response to each of the Error Handling options. For a multi-channel meter, the [Path
Error Handling] set to ON (see Figure 36) changes the Output response. See Table 4 for Analog Output response with
Path Error Handling set to ON.
Note:
Table 4 assumes Composite Actual Volumetric is chosen as Measurement for Analog Output.
Table 2: Measurement Options for Analog output
Measurement Channel Measurement Options for Analog Output
Composite Velocity, Actual Volumetric, Standard Volumetric, Mass Flow, Average
Volumetric Flow Rate, Sound speed, Reynolds#
Channel x Velocity, Actual Volumetric, Standard Volumetric, Mass Flow, Average
Volumetric Flow rate, Sound speed, Standard Deviation of Gain, Gain and
SNR

Option Output Response
Low Forces Output to 4mA on error
High Forces Output to 20mA on error
Hold Holds the last “good” reading
Other Enables the user to enter a value between 4mA and 20mA, to be output
during an error
