1.0 INTRODUCTION

The Checkline ETB/ETPB tension meters accurately measure tension on ne wires,

yarns and bers. Rollers or ceramic pins are mounted at the end of long “ngers”

permitting the user to measure tension with limited access space or when several lines

are closely spaced such as on a warp sheet.

Features include color, backlight TFT-display with 3 different displays modes: numeric,

numeric with live bargraph, numeric with graph (time vs tension). The display auto

rotates in 90° steps for optimal visibility regardless of the position of the tension meter.

1.1 Delivery

ET Series gauges are delivered as a complete kit

including tension meter, built-in rechargeable

battery and USB/AC adapter with country adapters

(EU, US, UK, AUS/NZ) and operating instructions

all supplied in a foam-tted carrying case.

Optional: NIST-Traceable Calibration Certication.

1.2 Precautions

The device must not be operated in potential explosive areas and must

not come into contact with aggressive substances.

Tensions that exceed the tension range of the instrument by more than

100% may cause permanent damage to the measuring spring and must

be avoided under any circumstances.

For cleaning the unit do not use any aggressive solvents such as

trichloroethylene or similar chemicals. No warranty or liability shall be

accepted for damage resulting from improper cleaning.

1.3 Veriﬁcation interval

The question of nding the right frequency of calibration accuracy verication depends

on several different factors: Operating time and load of the tension meter, olerance band

dened by the customer, hanges to the tolerance band compared to previous calibrations

Therefore, the interval between verications of calibration must be determined by the

user‘s Quality Assurance Department, based on the user‘s experience. Assuming normal

operating time and load as well as careful handling of the tension meter, we recommend

a verication interval of one year.

2.2 Removing the Filament Guide (see also section 8.0)

The tension meter is supplied with a lament guide for fast and easy material

acquisition. For application in hard-to-reach areas with limited access space, you can

remove the lament guide.

1. Loosen the grub screws (2x) with the supplied screwdriver (blade width 1.5 mm).

2. Unscrew and remove the guide rollers (2x) with the supplied open end wrench

(jaw width 4 mm).

3. Slip the lament guide off the roller shafts.

4. Screw the guide rollers (2x) back on to the roller shafts and carefully tighten them

with the supplied open end wrench (jaw width 4 mm) until hand-tight.

2.3 Mounting the Filament Guide

1. Unscrew and remove the guide rollers (2x) with the supplied open end wrench

(jaw width 4 mm).

2. Slip the lament guide on to the roller shafts.

3. Screw the guide rollers (2x) back on to the roller shafts and carefully tighten them

with the supplied open end wrench (jaw width 4 mm) until hand-tight.

4. Push the lament guide forward far enough to ensure that the rollers do not rub

against the lament guide and that the process material can slide unhindered from

the lament guide into the roller grooves (see fgure above, center line).

5. Carefully tighten the grub screws (2x) with the supplied screwdriver until hand-tight.

2.4 Display elements

Numeric Display

Display with Bar Graph

NOTE: The Y-axis can be scaled with the and buttons.

3 Scalings: total measuring range, set limits range plus approx. 1/3 of

MAX-alarm value and minus approx. 1/3 of MIN-alarm value, if limit

values are entered and the damping is not activated.

With the or button the X-axis can be scaled.

The setting range is 2 to 60 sec.

The scaling can also be changed during the measurement, whereby

values already displayed are deleted when the X-axis is changed.

3.0 SETUP

The tension meter is delivered with a built-in rechargeable LiPo battery, which has

been charged at the factory. The tension meter can only be switched on if the battery

has enough charge. If the instrument does not power up or if the battery level indicator

shows a low charge after power-up, the battery needs to be recharged.

To ensure maximum battery life, avoid discharging it completely or charging it

frequently for short periods. The battery should not be stored for a extended period of

time when empty. After a maximum storage period of one year, the battery has to be

recharged.

3.1 Charging the Battery

The battery can only be charged at a temperature between +5 °C and +45 °C.

Before you connect the AC adapter, verify that the supply voltage is correct

(100 V – 240 V).

To charge the battery, remove the rubber stopper from the USB interface. Then connect

the AC adapter cable to the USB output. The battery can also be charged by connecting

the USB cable to a PC. The battery level indicator will be shown full when the

battery is fully chaarged. The charging time is approx. 3 ½ hours (using the AC adapter).

NOTE: Battery overcharging is not possible

3.2 Switching the tension meter on

1. Press and hold the button (for approx. 1 sec.) until the DISPLAY shows the

measuring range, the software and hardware versions, e.g. E 1.0, and then “0”.

During startup, the tension meter performs an automatic zero adjustment. If the

tension meter does not display zero, perform a manual zero adjustment procedure

(see section 5.1).

NOTE: Holding the button makes the display freeze so that you can read the

measuring range and the software and hardware versions.

While switching on the tension meter, make sure not to move it. Otherwise, the

automatic zero adjustment will be faulty.

3.3 Switching the tension meter off

Automatic switch-off (if enabled): After an idle period of 3 minutes, the tension meter

switches off.

Manual switch-off: Press and hold the button for 5 seconds.

4.0 TENSION METER SETTINGS

1. Press the and buttons simultaneously to access the main menu.

2. The and buttons can be used to select the various menu items of the main

menu, the submenus and the settings menus.

3. Press the button to open the selected menu; by pressing the or button you

can close the menu without saving changes.

4. In menus with multi-digit elds (e.g. date) use the and buttons to move

forward and backward between digits.

5. Press the button to save the settings and exit the settings menu or press the

button to exit the current menu without saving.

6. To exit the main menu press the button.
