Safety Information

Use the instrument only as specied in this

manual. Otherwise, the protection provided by
the instrument may be impaired. Refer to safety
information in Table 1-1.

A Warning identies conditions and actions that
pose hazards to the user. A Caution identies

conditions and actions that may damage the
instrument or the equipment under test.

Table 1-1. Safety Information

Warning

To avoid personal injury or death, follow these
guidelines:

●

Most governments and legal authorities re­quire that HVAC technicians be trained and

certied in the safe and proper operation of

HVAC tools, such as this instrument. Since
this tool may be connected to many types of
equipment through a limitless combination

of hoses and ttings, proper training is the

most important element of using this tool
safely.

●

Read the entire Users Manual before using
the instrument.

●

Use the instrument only as described in the
Users Manual, otherwise the protection pro­vided by the equipment may be impaired.

Do not use the instrument if it is damaged.

●

Before you use the instrument, inspect the
case. Look for cracks or loose components.

Table 1-1. Safety Information

Warning

●

The instrument contains no internal user­serviceable parts other than batteries that
may be accessed through the battery door.
Do not open the instrument other than open­ing the battery door. Have the instrument
serviced only by Ritchie Engineering Co. or
authorized service centers.

●

Do not use the instrument if it operates ab­normally. Protection may be impaired. When
in doubt, have the instrument serviced.

●

Refer to warnings supplied with batteries
acquired for use in this instrument. If the bat­teries are not supplied with warnings, obtain
them from the manufacturer or supplier.

Do not operate the instrument or service bat-

●

teries around explosive gas, vapor, or dust.

●

Various refrigerants have been intentionally

excluded for very signicant safety reasons.

Never use refrigerants in this instrument that
are not listed in the Set-up menu.

●

The refrigerant database in this unit may

include refrigerants classied as ammable.

If such refrigerants are selected, the operator

may need additional certications and/or

training. Consult your government and legal
authority and comply fully with all require­ments.

●

Always wear eye and skin protection when
working with refrigerants. Escaping refriger­ant vapors will present a freezing danger.
Do not direct refrigerant vapors venting from
hoses towards the skin.

Maximum Working Pressure: High Side: 700

●

psia (4.83 MPa)

Maximum Working Pressure: Low Side: 350

●

psia (2.41 MPa)

●

Because this instrument allows for various
inputs including electrical and mechanical,
care must be taken to observe any ways that
an electrical shock hazard could develop.
Example: Wet or humid conditions, along
with a damaged thermocouple or vacuum
sensor, could allow an electrical path across
the instrument and over wet hoses. Keep all
interconnected equipment clean, organized,
and in proper condition. Do not use the in-

strument if you are not qualied to recognize

potential electrical faults.

Table 1-1. Safety Information

Caution

To avoid damage to equipment, follow these
guidelines:

Do not allow pressures beyond the speci-

●

cations listed in this manual.

●

Be aware that internal pressures can
change unintentionally when equipment is
stored with pressure in the system during
temperature changes. If sub-cooled liquid
refrigerant is trapped in a hose or manifold
with no room for expansion, it may result in
dramatic pressure variations with seemingly
small temperature changes. Pressures can
reach high enough levels to cause dam­age to the instrument’s internal pressure
transducers. Release liquid refrigerant from
the hoses and manifold when disconnecting
from a system.

Refer to cautions supplied with batteries

●

acquired for use in this instrument.

Do not attempt to introduce liquid or

●

samples heavily laden with oil into the
instrument.

●

Read and observe instructions and speci-

cations related to the batteries used in this
instrument that may cause damage to it.

Do not use this instrument on systems

●

containing leak sealing chemicals. These
leak sealants can collect and harden in the
instrument, causing permanent damage.

Chapter 2
Getting Acquainted

Introduction

This instrument will clearly and accurately report
critical information needed to properly service re­frigeration and air-conditioning equipment. With its
many features, time can be saved and the quality

of service can be veried through data reports for
customer satisfaction. Some of the most signi-

cant features include:

●

High accuracy and resolution

●

Very fast and sensitive leak detection

●

Robust temperature compensation with fault
detection

●

Data logging and downloading for reporting and
analysis

●

High durability and weather-resistance

Note that these instructions do not cover the
manifold attached to the instrument.

Turning the Instrument On
and Off

Press and release the key to turn unit on. After
the logo appears briey, the instrument will pres­ent the main menu.

Press and hold the key (~two seconds) to turn
unit off.

Battery Considerations

The instrument uses eight AA batteries. The
user may select batteries of the following types:
Alkaline, AA-Lithium, Ni-MH, Ni-Cd, Li-Pol, Li-Ion
from the Setup menu (see Chapter 5). Do not mix
battery types, including rating (i.e., do not mix four
Ni-MH rated at 1600mAh with four Ni-MH rated
at 1800mAh). Also, each battery in a set of eight
must be at the same power state, preferably fully
charged. The battery life indicator is only accurate
when the correct battery type is selected in the
SET-UP menu.

The illustration below shows three bars that indi­cate a fresh or well-charged battery pack. When
the battery weakens, the bars will disappear one­by-one as the battery power decays. When one
bar remains, the symbol will turn yellow. When all
bars are gone, the batteries are nearly dead and

the symbol will turn red. The unit will briey show

a pop-up message just before the unit stores all
data and then automatically shuts off.

Figure 2-2. Battery Power Symbol

Figure 2-3. Low Battery Pop-Up Message

Automatic Power Off

The instrument may automatically turn off after
a period of time. The default is one hour. The
user may select other settings from ten minutes
to four hours from the Setup menu (see Chapter

5). The user may also disable this feature. The
Auto Power Off time limit is automatically disabled
during data logging and is automatically restored
once data logging has terminated.

Power Saving Mode

The display backlight will fade, darkening the
display to save battery life if a key has not been
pressed for a set period of time. While in Power
Saving Mode, pressing any key turns the display
backlight back to full brightness. Note that
backlighting is independent from the display
brightness and contrast settings (see Chapter 5)
which do not affect battery life.

The Power Saving Mode is preset to 10 minutes.
From the Setup menu (see Chapter 5), you can
specify settings from 30 seconds to 60 minutes.

Low Battery Conditions

The unit will attempt to store all logged data if
low battery power is detected. Once the data is
stored, unit will turn off.

Maximizing Battery Life

Battery life decays fastest when the DIGITAL
MANIFOLD display is selected, the vacuum sen­sor is attached, and the backlight is on. Battery
life during data logging is maximized by using
high-performance batteries, detaching the vacuum
sensor (if not in use), and a short Power Saving
Mode time setting is selected.

Keyboard Keys

Note that pressing a key that has not been
assigned to a function will result in three, short
beeps.
