1. General Information
This manual contains technical and general information relating to the installation, operation, and calibration
of vacuum gauges and gauge tubes manufactured by Teledyne Hastings Instruments (THI).
For best performance, THI vacuum gauges should be operated with the appropriate THI gauge tube. Attempting
to use a THI vacuum gauge with another manufacturer’s tube may result in damage to the gauge and/or tube.
NOTICE: Contact with harsh solvents and chemicals to any plastic parts of the HPM 4/5/6
Vacuum Gauge can damage the unit and may void the warranty.
NOTICE: Instrument repair should only be performed by Teledyne Hastings service technicians.
NOTICE: Disconnecting the gauge tube by pulling on the cable may result in damage to the
device. Always disconnect by pulling directly on the octal connector.
CAUTION: There are no operator serviceable parts or adjustments inside the product.
CAUTION: If this equipment is used in a manner other than that specified, the protection
provided by the equipment may be impaired.
Features
The HPM 4/5/6 is a battery-operated hand-held vacuum gauge that supports the Teledyne Hastings DV-4, DV-5
and DV-6 series vacuum gauge tubes. It is designed for portability and ease of use in applications where AC
power is not readily available.
Digital circuitry powers the vacuum gauge tube and converts its output for display. The lightweight unit
operates with a standard 9-volt battery and can be configured to display in units of Torr, mbar, or Pascal.
The device can be calibrated from the front panel using an in-system vacuum tube at known vacuum or
out-of-system using a Hastings Reference Tube. Front panel buttons enable switching between DV-4, DV-5, and
DV-6 tubes. These tubes are rugged, noble-metal sensors which are resistant to corrosion and can be ordered
with a variety of system connections such as VCR®, KF-16, KF-25, Glass, MiniConflat™ and 1/8" NPT, etc.

Accessories
1.3.1. Installation Accessories
Teledyne Hastings Instruments offers a complete line of system attachments that permit easy
maintenance for contaminated operations. Gauge tubes are offered with various system fittings to match
almost any system requirement. Additionally, Teledyne Hastings’ complete line of quick disconnect
attachments allows customers to install these special fittings and easily replace sensors without vacuum
sealant or Teflon® tape. For particularly dirty systems, Teledyne Hastings offers a particle dropout trap
containing a series of nine separate baffles which prevent solid contaminants from having a direct path
to the sensor’s thermocouple.
1.3.2. Calibration Reference Tubes
Reference Tubes employ the same metal thermopiles used in all THI Vacuum Gauge Tubes. The thermopile is sealed
in a glass capsule that has been evacuated, baked, outgassed, and aged to ensure long-term stability. The sealed
capsule is housed in a rugged metal shell to provide a trouble-free assembly. The reference gauge tube is calibrated
to simulate a gauge tube at a given operating pressure (noted on the shell), and provides quick and easy adjustment.

2.3.1. Battery Life Notes
Battery life specifications are given at 20°C. If the HPM 4/5/6 is operated for a significant time at
temperatures much lower than this, battery life will be reduced. Alkaline batteries have an operating
temperature range of -18°C −55°C (0°F −130°F). Lithium (not lithium ion) 9-volt batteries (ANSI # 1604L)
are the recommended replacement when operating in cold or very warm temperatures. The operating
temperature for Lithium batteries is -20°C −60°C (-4°F −140°F). Lithium batteries have better cold-weather
behavior and longer battery life than alkali batteries at all temperatures.

Electrical Connector
Teledyne Hastings vacuum gauge tubes interface with the HPM 4/5/6 via the included octal connector. The
connector is “keyed” so that proper connection is assured (only fits the correct orientation). Always grip the
connector by its cover and not the cable when plugging or unplugging. In some cases, corrosion may build up on
the gauge tube pins. To ensure a good connection and accurate readings, use Scotch-Brite or an equivalent
abrasive to clean the pins when needed.
NOTICE: Disconnecting the gauge tube by pulling on the cable may result in damage to the octal socket
and/or cable. Always disconnect by pulling on the octal connector directly.

Digital AVC Instruction Manual
EAR99 Technology Subject to Restrictions Contained on the Cover Page Page 15 of 17
Thermal Coefficient
The HPM 4/5/6 generates an AC heating voltage using an internal transformer. This heating voltage is
supplied to the vacuum tube to warm up the thermocouples in order to measure the pressure. As the
ambient temperature increases or decreases the internal resistance of the copper winding in the
transformer also changes. This resistance change will change the AC heating voltage that the vacuum
tube receives and changes the pressure reading slightly.
Increasing temperature will cause the
pressure readings to increase and
decreasing temperature will cause
the pressure readings to decrease.
The chart to the right shows the
amplified output from the gauge tube
as the ambient temperature changes
from -25°C to 77°C. The instruments
are initially adjusted at an ambient
temperature of approximately 22°C.
The dominant effect is the change in
the zero-pressure output of the tube.
This effect can be corrected by
adjusting the low pressure reading at
the operating ambient temperature.
The mid-range of the tube is highly
immune to temperature changes. A
much smaller change will occur in the
highest-pressure area, but since the
curve is quite flat through this region,
a small change in output can cause a
significant change in the indicated
pressure reading.
The specified rate of change does not
include actual changes in pressure
that occur in a closed vacuum system
during temperature excursions.
The typical rate of change is as follows:
DV-4 (1.25% of reading + 2.2 mTorr)/°C
DV-5 (0.1% of reading + 0.08 mTorr)/°C
DV-6 (-0.21% of reading + 0.2 mTorr)/°C
