Flow Readout Box
1. APPLICATIONS & FEATURES
Flow Readout Boxes provide operating power supply, operating control, flow setting and flow digital display for
the mass flow controller (MFC) and the mass flow meter (MFM). D08 series of Flow Readout Boxes could directly
connected with D07 series MFC or MFM without any change. And it can also be used for other models of MFC or
MFM.
With standard desk-style section bar chassis, D08-2F, 3F, 4F Flow Readout box can control 2, 3 or 4 MFCs (or
MFMs). And each channels have the independent displays and control potentiometers.

4. STRUCTURE INSTRUCTION
4.1 ±15V Power Supply
Composed by three-terminal integrated stabilized modules, ±15V power supply with the simple connection, high
stability and reliability are available as well as over-heat and over-load protections in the integrated stabilized
electric circuit.
4.2 +5.00V Nominal Power Supply
From the +5.00V nominal power supply, the 0~5V voltage output which is adjusted by its set potentiometer can be
used for controlling MFCs. Because of the soft-start circuit, the voltage will rises gradually from 0 to +5V for
avoiding the overshoot of MFC responding. The time of soft-start will cost 20 seconds approximately.
4.3 Displayer
3 and 1/2 numbers panel can display the readout from MFC (The maximum value: 1800). Flow rate can be
displayed by “SCCM”, “SLM” or “%FS”. Normally, the default flow range and unit of Flow Displayer will be set
to the user want to. If the user cannot give MFC flow specifications, the default will be set as %FS. The SLM and
SCCM LBD in the frontal panel will indicate the flow unit. Two LBD off means that flow unit is %FS. The radix
point, unit of every channel could be adjusted respectively.
220VAC / 110VAC

4.4 Valve Controller
Valve Controller is used for selecting working status of MFC. When MFC is operated normally, it should be
“Valve Control”. If MFC valve need to be full opened, it should be “Purge”. MFC valve will be closed if it is
“OFF”. Caution: This function can be only available for D07 series MFC without any problems. For other MFC
products, please do NOT connect “ Valve Control” pin.
4.5 Zero Potentiometer
“Zero Potentiometer” can only adjust zero in a small range for D07 series MFC/MFM products. It will be useless
for other MFC products.
4.6 Setting Potentiometer
The user can use “setting potentiometer’ to send the voltage (0-5V) to MFC for setpoints.
4.7 Power Supply Switch
Power on or off the box.
4.8 Power Supply Connector
AC （~220V±10% 50Hz）should be imported by this connector.
4.9 Fuse
1A fuse tube is used. Please check the fuse if power of the box failure.
4.10 Setting Selection
“Setting selection” is used for selecting where the setting signal comes from. If it is set to “INT”, the “setting
potentiometer” of the box will control the MFC. Comparably if it is set to “EXT”, the control signal of MFC will
come from the “EXT control connector”.
4.11 MFC “D” Connector
15pin D connector is used for connection with the MFC/MFM. Every connector (channel) can only be connected to
one MFC. Thus, two channel for D08-2F, three channel for D08-3F, and four channel for D08-4F.
4.12 External Control Connector
The 0-5V voltage can be used for external control signal Please refer table 3 for connection.
4.13 Nameplate
Page 5 of 12
Nameplate indicates the actual situation of each MFC (or MFM) channel when flow readout box connected with
MFC (or MFM), for example the full scales and flow units.

Output and Signal Common. These signals must be
connected correctly.
②“Valve Drive” and “ External Zero Adjustment”
signals are only for D07 series MFC products. For
other MFC products, please do NOT connect
③GND Line normally is disconnected. (Please refer to
the MAINTENANCE information)
④For MFM, “Valve Drive ”and “Set” is invalid.
⑤If you provide your own cable for other MFC products,
we suggest that you only connect necessary signals as
in ①.
