General Information  
Introduction  
The Hastings Capacitance Manometer Power Supply (HCM-300) supplies stable  
±15VDC specifically for operating the Hastings Capacitance ManometerTrans-  
ducer.The transducer returns a signal to the HCM-300 which displays an accurate  
pressure reading.

Installation  
Receiving Inspection  
Carefully unpack the HCM-300. 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.  
 
Installation  
2-3  
To panel mount the HCM-300:  
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:

Cable Connections  
The HCM-300 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 cable connects the instrument to the transducer.The diagram below  
shows the proper connections.

Operating Information  
Normal Start-up  
1) Connect the interface cable from the HCM-300 to the transducer.  
(See figure on page 2-4 of this manual)  
2) Verify that the AC power to be applied to the HCM-300 is correct (115VAC).  
3) Apply AC power to the HCM-300.  
4) The HCM transducer has a local zero adjustment. Follow the zero  
adjustment procedure described in the HCM-6000 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  
which is not covered by the warranty.  
Analog Output  
The HCM-300 generates an analog signal which is directly proportional to the  
displayed pressure.The analog output signal is given by:  
(1)  
The output signal is a DC voltage with a full scale reading for a given capacitance  
manometer transducer corresponding to +10VDC. For example, if one has a 100  
Torr HCM transducer with a displayed pressure of 35Torr, then the output volt-  
age will be:  
(2)  
The uncertainty associated with the analog output voltage is given by:  
(3)  
 
Operating Information  
3-3  
Conversely, if the analog output voltage is measured, then the pressure reading is  
given by:  
(4)  
Internal Adjustments  
The internal adjustments are factory set and should never need to 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 +10VDC signal to the Sig Hi and Sig Lo pins on  
the back of the power supply.The display of the instrument should read “1000.0”,  
“100.00” or “10.000”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 transducer itself. See the  
HCM-6000 series transducer manual Section 3.

Operating Information  
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 configura-  
tion, this jumper can be easily moved (see figure below).

Maintainance and Repair  
Warranty Repair  
Hastings Instruments will repair or replace, at their option, any product covered  
under the warranty expressed in the front of this manual, that is returned transpor-  
tation prepaid to their plant in Hampton,Virginia. All products returned must be  
accompanied by a Return Materials Authorization (RMA) form or a written  
description of the problem with the instrument. Please consult the factory for your  
RMA number before returning any product for repair.  
Non-Warranty Repair  
Any product returned for a non-warranty repair must be accompanied by a pur-  
chase order authorizing repair up to 1/3 the list cost of a new product and the  
RMA form or 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 have the product repaired, a minimum  
will be charged to cover the processing and inspection. Please consult the factory  
for your RMA number before returning any product for repair.
