Table 1-1. Safety Information
Caution
To avoid damage to equipment, follow these
guidelines:
Do not allow pressures beyond the specifi-
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 dam-
age 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 specifi-
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.

Getting Acquainted
Introduction
This instrument will clearly and accurately report
critical information needed to properly service re-
frigeration and air-conditioning equipment. With its
many features, time can be saved and the quality
of service can be verified through data reports for
customer satisfaction. Some of the most signifi-
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 briefly, the instrument will pres-
ent 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.
