General Information
Introduction
The Hastings Power Supply (HPS-10) supplies stable ±15VDC specifically for Hastings mass
flowmeters (HFM-200 and HFM-300 series). The flowmeter returns a 0-5VDC output that is
proportional to flow that is digitally displayed.

Installation
Receiving Inspection
Carefully unpack the HPS-10. Inspect all items received at this time for any obvious damage that
may have occurred during shipment. Immediately advise the shipping agent if there is any damage
to items in your shipment. Identify each item and the quantity received with those listed on the
packing list.
Mounting
Cut out panel as shown in the diagram below.
page 7
To panel mount the HPS-10:
1) Slide power supply into panel from the front.
2) Attach brackets to the side of the power supply.
3) Tighten screws against panel.
See Figure below:

Hastings HPS-10 Power Supply Cable Connections
The HPS-10 is supplied with a power cable.The 3-wire cable plugs into the back of the instrument
in the socket marked“AC POWER”.
A 5-wire shielded cable connects the instrument to the flowmeter.The diagram below shows the
proper connections.

Operating Information
Normal Start-up
1) Connect the interface cable from the HPS-10 to the flowmeter. (See figure on page 2-4 of
this manual)
2) Verify that the AC power to be applied to the HPS-10 is correct (115VAC).
3) Apply AC power to the HPS-10.
4) The HFM instrument has a local zero adjustment. Follow the zero adjustment procedure
described in the HFM-200 or HFM-300 series manual.
Caution
Before applying power to the instrument, ensure that the line voltage being
applied is correct. Failure to do so may result in damage to the instrument
not covered by the warranty.
Analog Output
The HPS-10 generates an analog signal which is directly proportional to the displayed pressure.
The analog output signal is given by:
DISPLAY GAS FLOW
FLOWMETER RANGE
V
5
OUT
*
The output signal is a DC voltage with a full scale reading for a given flowmeter corresponding to
+5VDC. For example, if one has a 100 sccm flowmeter with a displayed flow of 35 sccm, then the
output voltage will be:
35 sccm
100 sccm
V
5
1.75Volts
OUT
*
Conversely, if the analog output voltage is measured, then the gas flow reading is given by:
V
OUT (V)*FLOWMETER RANGE
GAS FLOW

Internal Adjustments
The internal adjustments are factory set and should not be changed. However, if the need arises
and suitable standards are available the following adjustments can be made. (see figure on page 3-4)
Full Scale
The full scale potentiometer changes the display by changing the sensitivity of the instrument.
Apply a calibrated +5 VDC signal to the Sig Hi and Sig Lo pins on the back of the power
supply.The display of the instrument should read“100.0”,“10.00”or “1.000”depending upon the
configuration.Adjust the full scale potentiometer (R11) if needed.
Analog Output
The analog output potentiometer changes the analog output voltage by changing the gain on the
output buffer amplifier. Apply a calibrated pressure standard to the transducer and refer to
equation (1). Adjust the potentiometer (R18) as needed.
Notes on internal adjustments:
*
Both the full scale reading and the analog output voltage can change by only ± 10%.
** Zero adjustment can only be performed on the flowmeter itself. Consult your flowmeters
manual for making these adjustments.
Display Configuration
The jumper position on the power supply circuit board determines the location of the decimal on
the display.The jumper is factory set to match the configuration specified by the customer. Should
the need arise to change the display configuration, this jumper can be easily moved (see figure on
page 13).

warranty does not apply to batteries or other expendable parts, nor to damage caused by leaking
batteries or any similar occurrence.This warranty does not apply to any instrument which has had
a tamper seal removed or broken.
This warranty is in lieu of all other warranties, expressed or implied, including any implied warranty
as to fitness for a particular use. Hastings Instruments shall not be liable for any indirect or conse-
quential damages.
Hastings Instruments will, at its option, repair, replace or refund the selling price of the product if
Hastings Instruments determines, in good faith, that it is defective in materials or workmanship
during the warranty period. Defective instruments should be returned to Hastings Instruments
together with a written statement of the problem and a Return MaterialAuthorization (RMA)
number. Please consult the factory for your RMA number before returning any product for repair.
Non-Warranty Repair Policy
Any product returned for a non-warranty repair must be accompanied by a purchase order, RMA
form and a written description of the problem with the instrument. If the repair cost is higher, you
will be contacted for authorization before we proceed with any repairs. If you then choose not to
