D e s c r i p t i o n o f C a u t i o n / W a r n i n g S y m b o l s
Appropriate caution/warning statements are used throughout the manual
and on the instrument that require you to take cautionary measures when
working with the instrument.
Caution
C a u t i o n
Failure to follow the procedures prescribed in this manual might result in
irreparable equipment damage. Important information about the operation
and maintenance of this instrument is included in this manual.
Warning
W A R N I N G
Warning means that unsafe use of the instrument could result in serious
injury to you or cause damage to the instrument. Follow the procedures
prescribed.
Caution or Warning Symbols
The following symbols may accompany cautions and warnings to indicate
the nature and consequences of hazards:
Warns that uninsulated voltage within the instrument may
have sufficient magnitude to cause electric shock.
Therefore, it is dangerous to make contact with any part
inside the instrument.
Warns that the instrument is susceptible to electro-static
dissipation (ESD) and ESD protection procedures should be
followed to avoid damage.
Indicates the connector is connected to earth ground and
cabinet ground.
Carefully read each of the following safety warnings prior
to using the HM675 Hydronic Manometer.
W A R N I N G
Never use the HM675 Hydronic Manometer or accessories on potable
water systems or other systems which may be used to convey fluids for
human or animal consumption.
W A R N I N G
Never charge non-rechargeable batteries by setting battery-type
selection switch to NiMH when using alkaline or other non-rechargeable
batteries. Fire, explosions, or other hazards may result.

vii
C a u t i o n
Never use the HM675 Hydronic Manometer to measure the pressure of
volatile, flammable, or otherwise hazardous fluids or gasses. The
instrument is not designed to be intrinsically safe, nor is it designed for
use with caustic or corrosive chemicals.
C a u t i o n
Never connect the HM675 Hydronic Manometer or accessories to
systems which exceed the instrument’s maximum pressure specification
(300 psi; 2068 kPa).
C a u t i o n
Observe proper safety precautions and wear appropriate personal
protective equipment, including gloves and eyewear, when working on
high pressure or high temperature systems. Ruptured or leaking lines
pose a potential risk of serious personal injury.
C a u t i o n
When using the HM675 Hydronic Manometer, verify all hose connections
are secure prior to taking pressure measurements. Loose connections
may result in the discharge of pressurized water or air, posing a potential
risk of serious personal injury.
C a u t i o n
Exercise caution when disconnecting the HM675 Hydronic Manometer
from a pressurized system. Water or air discharged under pressure
poses a potential risk of severe injury.
C a u t i o n
Exercise caution in using the HM675 Hydronic Manometer near electrical
equipment. Water spray associated with purging or disconnecting hoses
presents a potential risk of damage to such equipment.
C a u t i o n
Thoroughly drain and dry the HM675 Hydronic Manometer hoses and
internal piping after each use. This will help in limiting the potential for
growth of hazardous microorganisms.
C a u t i o n
Never plug into the instrument any power supply other than the one
provided with the instrument.
C a u t i o n
Always make certain that the battery switch is in the correct position for
the type of battery being used (Alkaline/NiMH). Failure to do so may
result in Fire, Explosions or other hazard.

viii Hydronic Manometer Model HM675
C a u t i o n
Never use Alkaline and NiMH batteries together on the same instrument.
C a u t i o n
Always use the hoses with the provided Flow Restrictor connected in line
with the shut-off valves to prevent “Water Hammer.” Water Hammer is a
fast moving shock wave of pressure caused by sudden changes in the
system such as a valve being opened or closed or a pump being turned
on or off.

TIME
CONSTANT
Pressing the TIME CONSTANT key allows for toggling
through the available settings for the time constant (TC) as
follows: 1, 5, 10, 20, and 30 seconds. The current setting of
the time constant is indicated on the display.
Notes:
The time constant is the sampling period over which the
manometer averages pressure measurements. Example:
with the time constant equal to 10 seconds, the
displayed reading represents the average of
measurements taken over the previous 10 seconds.
Increasing the time constant will serve to improve
measurement stability, particularly when measuring
systems with fluctuating pressures.
CONTRAST

Press the CONTRAST ▲ key to increase the display
contrast.
CONTRAST

Press the CONTRAST ▼ key to decrease the display
contrast.
Press the key to turn the HM675 Hydronic Manometer
on or off.
Press the BACKLIGHT key to turn the display’s backlighting
on or off.
Note: Backlighting has a significant impact on battery life.
Use backlighting only when working in areas where
you cannot read the display with existing light.
P o w e r i n g t h e I n s t r u m e n t
The HM675 Hydronic Manometer can be powered by four (4) AA-size
batteries (alkaline or rechargeable NiMH) or the AC adapter.
Using the AC Adapter
The AC adapter allows the HM675 Hydronic Manometer to be powered
from a standard AC wall outlet. When using the AC adapter, alkaline
batteries (if installed) will be bypassed. The AC adapter also charges the
NiMH type batteries (if installed) in the unit.
Note With the battery-type selection switch set to NiMH, the manometer
will initiate charging the batteries whenever the AC adapter is
connected.
