Adhesion/Release Tester Operating Instructions (AR-2000)

PRODUCT DESCRIPTION

Congratulations on the purchase of your new ChemInstruments AR-2000

Adhesion/Release Tester. This versatile, user-friendly, carefully designed instrument

allows you to determine adhesion and release values of adhesive laminates at various

speeds and at various angles of separation.

WARNING: This equipment can cause injury if not used properly. It is

the operator’s responsibility to observe all safety rules and warnings.

The unit has the following features:

•2 modes of operation: constant speed and ramped speed testing.

•Selectable testing speeds.

•Selectable separation angles from 90 degrees to 180 degrees.

•User-selectable data acquisition area on the test sample.

•Selectable units of measure: Kilograms, Grams, Newtons, Pounds, & Ounces.

•Compatible with EZ Data System software. See www.cheminstruments.com for

details.

UNPACKING

ChemInstruments has made every effort to ensure that the AR-2000 arrives at your

location without damage. Carefully unpack the instrument and check for any damage

that may have occurred during shipment. If any damage did occur during transit, notify

the carrier immediately.

The ChemInstruments AR-2000 consists of the following parts:

•The test frame, which includes the motor/drive mechanism and the data

acquisition system.

•An envelope with this manual.

•The mast for mounting the load cell assembly.(Strapped to the wood 2x2

bracing)

Within the crate is a small box containing the following parts:

•The pivoting bracket and attached load cell assembly with calibration bracket and

wire.

•Power cord.

Make sure all of these components are present before discarding packaging material.

ASSEMBLY

WARNING: Due to its weight and size, use two people to move the AR-

2000.

Carefully remove the test frame/drive/data acquisition assembly from the packaging and

set them on a sturdy bench top. Check the physical dimensions listed previously for the

space required for the instrument. As with any precision piece of laboratory equipment,

it is preferable to locate the AR-2000 in an area where temperature and humidity are

controlled to standard conditions of 72 ± 2 degrees Fahrenheit and 50 ± 5% relative

humidity.

ATTACHING MAST AND LOAD CELL ASSEMBLY

Attach the mast to the test frame using the small clamping knobs that are included.

Make sure the mast is mounted with the flat side on the backside as shown in Figure 2.

The attachment holes for the mast are located on the back panel of the test frame

toward the left end of the frame when viewed from the back.

NOTE: If the tests to be run use relatively short sample strips at 90°or 180°, mount the

mast using the holes marked “C” in Figure 1. If testing longer strips, mount the mast

using holes marked “B” in Figure 1.

Slide the pivoting bracket with load cell assembly onto the mast and tighten the large

clamping bolt that is part of the assembly. On the side panel of the AR-2000, one end

of the load cell cable is permanently attached. Plug the free end of this cable into the

socket on the load cell assembly. (See Figure 2)

ATTACHING SWITCHES

One end of the control cable is also permanently attached to the side panel of the

control cabinet. The free end of this cable terminates in three white reed switches,

marked “Home”, “Start” and “Stop”. Each of these reed switches carries a piece of

Velcro®fastener that is designed to attach to the fastener tape located on the back rail

of the test frame. Attach the reed switch marked “Home” to this tape at the right end of

the test frame. Attach the reed switch marked “Start” to this tape at a location

approximately 2 inches to the left of the “Home” switch. Attach the reed switch marked

“Stop” to this tape at a location approximately even with the side of the control cabinet.

See Figure 2 for switch locations.

CONNECTING THE POWER CORD

WARNING: Make sure the power source matches the requirements of the

Adhesion Release Tester. Damage will occur if this unit is plugged into

the incorrect power supply. The AR-2000 is NOT a dual voltage machine.

Connect the power cord to its receptacle on the backside of the control cabinet at the far

right side when viewed from the rear. Complete the connection by inserting the male

end of the power cord into a convenient AC outlet. Notice that the on/off power switch

is located directly beside the power cord receptacle on the backside of the test frame.

WARNING: Before proceeding with using the AR-2000, it is advisable to

become familiar with the Key Components. These Key Components and

a brief description of their function follow in the next section.

Adhesion/Release Tester Operating Instructions (AR-2000)

KEY COMPONENTS

•POWER SWITCHis located on the back panel of the control cabinet directly

beside the power cord connection.(See Figure 3)

•FUNCTION SWITCHES control the start and stop of data acquisition. The

“Home” switch cycles the data acquisition unit into its “ready” mode. The “Start”

switch starts the data acquisition and the “Stop” switch stops the data acquisition.

(See Figure 2)

•TEST SLED provides a surface to hold the test material.

•EDGE BRACKETS hold test panels in place on the test sled.

•CLUTCH HANDLE engages and disengages the test sled with the drive chain.

The clutch handle is disengaged when the handle is to the left. The clutch

handle is engaged when the handle is to the right. The clutch handle is

disengaged in the photo below.

•MAST holds the pivoting bracket with load cell assembly and permits running

tests at angles between 90° and 180°. A small peg on the backside of the mast

allows for convenient positioning of the load cell for testing at a 180° angle.
