LOOP Menu
Loop Source
In ADVANCED Mode, select COMPLETION or FLOW RATE. In
SIMPLE Mode, only COMPLETION is available for the loop source.
mA at Completion
Shown if COMPLETION is selected. Enter mA value to be
output when batch is completed. Select 4.0 mA or 20 mA.
Error Value
Shown if COMPLETION is selected. Set desired Loop output value
when sensor error (e.g., bad sensor, broken wire) is detected. Select 3.6 mA, 22 mA,
NONE. Default = 3.6.
4 mA Setpoint
Shown if FLOW RATE is selected. Set
fl
ow rate value
corresponding to desired 4 mA output. Default = 0.
20 mA Setpoint
Shown if FLOW RATE is selected. Set
fl
ow rate value
corresponding to desired 20 mA output. Default = 100.
Adjust 4 mA
Allows
fi
ne-tuning to compensate for errors in other equipment
connected to the DPU91. The display value represents the precise current output.
Adjustment limits: 3.80 mA to 5.00 mA. Default = 4.00 mA.
Adjust 20 mA
Allows
fi
ne-tuning to compensate for errors in other equipment
connected to the DPU91. The display value represents the precise current output.
Adjustment limits: 19.00 mA to 21.00 mA. Default = 20 mA.
Test Loop
Press
▲
or
▼
to manually output a current value from 3.6 mA to 21.00
mA to test the output loop.
INPUT Menu - continued
Mode Select
Select ADVANCED or SIMPLE Mode. ADVANCED Mode enables
additional features in RELAY and LOOP Modes. Default = SIMPLE.
Count Up/Down
Select count direction of Batch Volume and Percent Complete
(Source Volume always counts down). Default = Count Up.
Missing Signal?
Determines if a Batch is stopped when No Flow is detected.
If YES is selected, Batch will be stopped; if NO is selected, Batch will continue.
Default = NO.
Note:
This setting is independent of Missing Signal Relay Mode; see page 19.
Set On Delay
Shown if MISSING SIGNAL is set to YES. Set desired ON delay
time in seconds. Default = 6 sec.
Select Batch Type
To change desired instrument type (i.e., Flow, pH, etc.). The
bottom line will display ALL SETTINGS WILL BE RESET. ARE YOU SURE? The
top line of the display will blink NO. Press
▼
or
▲
to select YES. Press ENTER
again to
fi
nalize your selection. For other DPU91 instruments, BATCH will be
displayed only when the Batch Module is installed.
