Section 2
Note that the flowmeter recognizes the first analog input variable that is assigned to any given param-
eter and ignores any subsequent input with the same assignment. For example, if Iin1 and Iin2 are both
assigned to represent Supply Temperature (Ts Deg F), the meter will only use the Supply Temperature
input from Iin1.
[Pc kW] Menu Cell
The [Pc kW] menu cell represents power consumption in kilowatts. When assigned to an analog input
this parameter will be used to compute chiller or heating efficiency (see paragraph 2.6.8).
Setting up the Analog Current Input
The first step is to enable the DC current input port.
From Analog Input setup:
To access the [Iin] option list press twice.
Move the cursor down to [Aux (n)] by pressing and then . This enables the port to
receive an input current. The cursor moves to [4 mA].
To enable numeric entry press . Type a numeric value corresponding to a 4 mA input
signal. To store the data press . This moves the cursor to [20 mA].
To enable numeric entry press . Type the numeric value corresponding to a 20 mA
input signal. To store the data, press .
2.11 THE DIAGNOSTICS DATA MENU
Some Diagnostic Data items require a successful transducer installation and meter initialization to be-
come available. These will report [Chan Not Setup] until you complete the installation procedure.
The Diagnostics Data menu provides real-time application and setup data, plus test routines for the
selected channel. To receive the best technical support, please be prepared to report any diagnostic data
item upon request. Note also that these menus contain information that may only be meaningful to our
technical support staff.
The available diagnostic data depends on the meter type and channel configuration. All diagnostics are
available when you select channel 1 or 2 in [Dual Channel Flow], [Ch 1+2 Flow] or [Ch 1-2 Flow]
modes. In [Dual Beam Flow] mode, all diagnostic items are available for [Path 1] or [Path 2]. Some items
are not available (N/A) when you select virtual channel [1 and 2]. In addition, selecting virtual Channel 3,
in either the [1+2 Flow] or [1-2 Flow] modes will limit the list to flow data only.
