SECTION 1  
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.

Power input ............................................................................................. 115VAC ±10%, 50/60 Hz  
Signal input ..................................................................................................................... 0 - 5VDC  
Display ............................................................................................................................... 3½ digit  
Analog output voltage ..................................................................................................... 0 - 5VDC  
Min. load impedance ............................................................................................................. 10 kW  
Display type......................................................................................... 0.52” (13.2mm) red LEDs  
Warm up time ......................................................................................................................15 min  
Operating temperature...................................................................................................... 0 - 500C  
Load regulation.............................................................................................. ±1% (10 mA-30 mA)

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.

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.

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 markedAC POWER”.  
A 5-wire shielded cable connects the instrument to the flowmeter.The diagram below shows the  
proper connections.

SECTION 3  
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 read100.0”,10.00or “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).
