1. Foreword
Thank you for your selection of the mass flow meter/controller Model 8700 Series. Prior to using
your new equipment, please read this manual thoroughly to ensure it is used in the correct way.
2. Precautions for Use
(1) Peripheral Equipment to Connect
① The connector pin assignment of Model 8700 Series is different from that of
Model 8500 Series and D8500 Series. For details, refer to 7. Connector and Pin
Assignment.
② Model 8700 Series allows the use of the same AC adapter as that for Model 8500
Series and D8500 Series. (The outside of the jack is +24 V.)
③ Check to see if the voltage (24 VDC), polarity and current capacity (0.3A or over)
of the power supply are correct.
④ Check to see if the analog set input is the signal within the allowable input range.
The allowable maximum input voltage is10 V and the allowable maximum input
current is 30 mA.
⑤ When the analog flow rate output signal is to be used, make sure that the proof
pressure on the input equipment side is sufficient. The output may possibly be in
a range of -1 to 7 V in the case of voltage and 0 to 26 mA in the case of current.
(2) Items to Check about the Product
Do the specifications shown on the label match your order?
(The ordered product has been assembled and adjusted one by one according to the
specifications. The ID plate attached to the back of the case shows the gases to use,
flow rate and other specifications. Check to see if they comply with your order
specifications.)

② Fluid name
③ Flow rate/calibration temperature
SCCM = ml/min at 0 ℃ : 1 atm
SLM = l/min at 0 ℃ : 1 atm
NCCM = ml/min at 20 ℃ : 1 atm
NLM = l/min at 20 ℃ : 1 atm
※ ”SCCM” stands for Standard Cubic Centimeter per Minute and normally refers to the
state at 0 ℃ , but there are many industries where the normal state is at 20 ℃ .
KOFLOC indicates the units of flow rate together with the calibration
temperature and atmosphere.
