2. Operation

2.1 Choose model

This series has a variety of models can be selected, different models corresponding to different capacity and resolution,
as shown in table on back cover of this manual.

2.2 Choose measuring adapters

In order to complete the test work convenient, the force gauge equipped with a variety of adapters. Select the
appropriate adaptors according to the actual need.

2.3 Power on/off

Touch for 2 seconds to power On or Off.

The indicator can identify the load cell. You should check the model wheith it is you want.
Check Battery Icon. If the power is low, should be recharged.

2.4 Testing

2.4.1 Adaptor

Select the appropriate adaptor, install it in the measurement axis of the load cell. Tighten it by hand, without the use of
tools. Do not use a deformed or damaged adaptor.

NOTE: Do not use tools to vigorously tighten the adaptor, otherwise it will damage the force gauge.

2.4.2 Select Units

The force gauge has a variety of measurement units, select the appropriate unit of force. (See 3.2.1 Unit )

2.4.3 Select Test Mode

5

This series force gauge has 4 kinds of measurement test mode can choose.

You can select it by touching under the meas ure interface,
Or can change it in menus (See 3.2.4 Test Mode ).

Track: The real time measuring mode, under this mode, press the zero key the force gauge will be cleared

(remove tare).

Peak: Peak readings will not change until a higher value is measured. Under this mode, touch the zero key

the force gauge will update the display immediately.

Auto-Peak: In this mode, the gauge display a peak value of force in a fixed duration. The duration time can be

set in menus.

First Peak: In this mode, the gauge can capture the first peak value of force, when the force value decreased to

reach the drop ratio. The drop ratio can be set in menus.

2.4.4 Set Tolerance Limit

The tolerance limits can be set for GO/NG measurement also.

If you set the alarm on and a valid limit, The icon , , will be displayed for within limit, lower than lower limit

or exceed upper limit.

2.4.5 Zeroing

Touch to clear the force gauge in track mode for removing the tare.

2.5 St or age

Measured results can be stored in the force gauge, so that you can review or print them later.

Under the measure interface, touch to save value measured, and the save icon will be displayed.

2.6 Browse and Printing

The values saved in memory can be reviewed in Browse function, see 3.3.2 Browse Data for detail.
The data in memory can be printed to a report, see 3.4 Printing for detail.
