Output Setup
The meter output can be analog via the 4-20 mA or digital via the USB or RS-485. The
4-20 mA hardware is pre-calibrated at the factory. You may optionally re-calibrate with
a 4 ½ digit multi-meter. This procedure is described in the manual. The output range of
the 4-20 mA needs to be specified. If the serial output with RS-485 is used you must
program the protocol, baud rate, device address. The digital output (DO) must be
configured to assign the SSR number to the alarm number and its activation logic.
Analog Output Range. The analog output range (4.00 mA = yy flow, 20.00 mA =
zz flow) is programmed using the following sequence from the keypad: You will need to
program your receiving device for the same range.
Enter Program Mode by pressing P then the access code and E then advance the
major menus using the P key till you see the menu “SET ANALOG OUTPUTS”
now your press E to enter, then select the output channel to program, by typing
the number or use the ^ v keys then press E. Now you assign the meter # you
want to this output channel. For the MFT line, #1 meter is the flow and #2 is the
temperature. In the 155 Flow Computer, you have up to 16 meters that are
completely programmable to their output being, velocity, flow, temperature,
average of other meters etc. Next you see the menu “OUT # NEXT TYPE ^ v
____” Flow or VELOCITY on an insertion meter. The screen will show “LOW
= 0.000 SCFM AT 4 mA” and you can enter whatever value you like followed
by the E key for the low current value which will state new value accepted if you
make a change. The next menu will read: “HIGH = YYY.YY SCFM AT 20
mA”. Again you enter the new value followed by E to make a change. The next
analog output channel will come up and your can select this with the E or escape
using the
C key multiple times.
