Chapter 1. Safety

Safety Warnings

Carefully read each of the following safety warnings prior

to using the HM680 Hydronic Manometer.

 Never use the HM680 Hydronic Manometer or accessories on potable water systems or other systems

which may be used to convey fluids for human or animal consumption.

 Never use the HM680 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.

 Never connect the HM680 Hydronic Manometer or accessories to systems which exceed the

instrument’s maximum pressure specification (300 psi; 2068 kPa).

 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.

 When using the HM680 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.

 Exercise caution when disconnecting the HM680 Hydronic Manometer from a pressurized system.

Water or air discharged under pressure poses a potential risk of serious personal injury.

 Exercise caution in using the HM680 Hydronic Manometer near electrical equipment. Water spray

associated with purging or disconnecting hoses presents a potential risk of damage to such equipment.

 Thoroughly drain and dry the HM680 Hydronic Manometer hoses and internal piping after each use.

This will help in limiting the potential for growth of hazardous microorganisms.

Chapter 2. Introduction

The HM680 Hydronic Manometer is an easy-to-use instrument designed for the accurate measurement of pressure and calculation of flow in non-potable water and air systems. Features of the manometer include the following:

 Single-function keys for ease of use

 Simultaneous measurement and display of High-side gauge and Differential pressure

 Direct calculation and display of Low-side gauge pressure

 Direct calculation and display of flow

 Automatic density corrected readings

 Data logging with calculated statistics

 Output port for downloading stored data to a computer

 User-selectable units of measure

 User-selectable time constant

 Easy-to-read, dot matrix LCD with backlight

 Power supplied via AC adapter or batteries (alkaline or rechargeable NiMH)

 Internal NiMH battery charging

 Automatic power shutoff

 Splash-proof case

 Rugged carrying case for storage of meter, hoses, accessories, tools, and paperwork

 6-inch temperature probe

Chapter 3. Getting Started

Keypad

Each key and its function is described below.

▲▼

The ▲and ▼keys are used to navigate through menus or to select an item to change. When entering text, these keys change the highlighted letter/number.

◄►

The ◄ and ► keys are used to change the selected item. When entering text, these keys are used to index the cursor to the desired location.

ESC

The ESC key is used to return to the previous screen or to cancel an operation without saving changes made to displayed information.

The ENTER key is used to select a menu item, or to accept changes made within a menu item and return to the previous screen. From either the Pressure or Flow Measurement screens, pressing the

ENTER key accesses the Main Menu.

READ

Pressing the READ key initiates taking a time-averaged reading based on the current time constant setting. After taking the reading, the values are stored to memory (current Test ID) and displayed on screen for a period of ten (10) seconds or until the READ key has been pressed again.

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.

DATA

Pressing the DATA key from either the Pressure or Flow Measurement screens provides access to the Data Logging Menu.

PRESS

Pressing the PRESS key from the Flow Measurement screen provides access to the Pressure Measurement screen.

ON/OFF Press the ON/OFF key to turn the HM680 Hydronic Manometer on or off.

CALC

Pressing the CALC key from either the Pressure or Flow Measurement screens provides access to the Calculations Menu.

FLOW

Pressing the FLOW key from the Pressure Measurement screen provides access to the Flow Measurement screen.

Powering the Instrument

The HM680 Hydronic Manometer is equipped to be powered either by four (4) AA-size batteries (alkaline or rechargeable NiMH) or the AC adapter.

Using the AC Adapter

The AC adapter allows the HM680 Hydronic Manometer to be powered from a standard AC wall outlet. When using the AC adapter, the 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.

Installing the Batteries

To install/replace the batteries:

1. Turn the manometer off and locate the battery cover on the back of the unit.

2. Loosen the screw on the battery compartment cover and lift to remove.

3. Remove the battery holder. Tapping the backside of the meter against your hand may assist in

removing the battery holder.

4. Remove the old batteries and replace with fresh batteries (alkaline or rechargeable NiMH). Ensure

that the batteries are correctly oriented within the battery holder.

5. Set the battery-type selection switch to indicate the type of batteries to be used (alkaline or

rechargeable NiMH).
