201/203/205/207 Series Flowmeters and Controllers Instruction Manual
2. Installation and Setup
This section contains the necessary steps to install a new flow meter/controller into operation as quickly and
easily as possible. Please read the following thoroughly before attempting to install the instrument.
Receiving Inspection
Prior to opening, inspect for obvious signs of damage to the shipment. Immediately advise the carrier who
delivered the shipment if any damage is suspected. If the shipment has arrived intact, carefully unpack the
instrument and any accessories that have been ordered. Check each component shipped with the packing list.
Ensure that all parts are present (i.e. flowmeter, controller, power supply, cables, etc.). Optional equipment
or accessories will be listed separately on the packing list. There may also be one or more OPT (option) items
on the packing list. These normally refer to special ranges or special gas calibrations. They may also refer to
special helium leak tests, or high pressure tests. In most cases, these are not separate parts, but special
options or modifications built into the flow instrument.
Power Requirements
See specifications in sections 1.2 and 1.3. The HFM-200/HFC-202 Series supply voltages should be reasonably
regulated as power supply ripple may propagate to the output. Surge suppressors are recommended to prevent
power spikes reaching the instrument. The Hastings power supplies in Section 1.5.1 satisfy these
requirements. Hastings power supplies are limited to no more than 150VA max and it is strongly recommended
that power supplies used with 200 Series instruments meet the recommendations in section 1.5.1.
NOTICE: Use of an underpowered or under-voltage supply could result in equipment damage.
2.2.1.
±15 VDC Option
The supply voltage for bipolar units (±15 VDC option) can vary in magnitude from 14.0 to 16.0 VDC. The
table below shows the recommended current draw and power requirements for ±15 VDC 200 series boards.

2.2.2.
24 VDC Option
The recommended operating range of 24V units is 11 to 36 VDC for meters, 12 to 36 VDC for 0-5 V
controllers, and 13 to 36 VDC for 4-20 mA controllers.
