- NOTICE -

Force reading accuracy may be affected by a low battery condition. BEFORE using the force gauge for the first time, fully charge the rechargeable NiCd battery. Plug the charger into the gauge’s charge jack and into an

AC outlet.

Always charge the battery whenever the BAT indicator is highlited. A minimum charge of 8 hours is recommended.

INTRODUCTION

The CHATILLON ® DFM Series (or CADET ® CD1 Series) has been designed to be easy to setup, operate and maintain. The instrument is ideal for tensile or compression measurement. The instrument may be supplied for either 110V or 220V operation. Four base models are available for both the CHATILLON and CADET brands, each model is distringuished by a different capacity. Capacities may be displayed in either lbs, kg or N measurements.

The instrument is supplied with a carrying case, battery charger, hex key, extension rod, hook and flat head attachments.

HANDHELD SETUP

The DFM/CD1 features a reversible split housing. The DFM/CD1 is factory assembled with the shaft pointed down for stand mounting applications. If the gauge is to be used for handheld testing, it may be desireable to reorient the shaft so that it points upward.

-WARNING -

Extreme care should be taken when removing the housing. Make sure that you do not pull, twist or pinch any of the wires inside the housing.

To change the shaft orientation perform the following:

1.

Remove the two hex screws on the backside of the bottom housing using the Hex Key provided with your gauge.

2.

Carefully, rotate the top housing 180-degrees making sure not to bind, twist or pull any of the wires.

3.

Reassemble the housing, making sure that no wires are pinched between the top and bottom housings.

-WARNING -

Force reading accuracy may be affected by a low battery condition. BEFORE using the force gauge for the first time, fully charge the rechargeable NiCd battery. Plug the charger into the gauge’s charge jack and into an

AC outlet.

Always charge the battery whenever the BAT indicator is highlited. A minimum charge of 8 hours is recommended.

Select PEAK until desired TYPE is highlited

< NORM, T-PK, C-PK>

Select ZERO to tare and reset the displayed value.

Zero All Force Values simultaneously.

Reset Current Peak Reading value.

-NOTICE -

Always apply load axially. Applying load on an angle or ecentric loading may cause an erroneous force reading.

OVERLOAD CONDITIONS

Extreme care should be taken to ensure that you do not overload the loadcell. Overload protection up to 175% of the gauge’s capacity is provided in compression mode only, however, any overload condition may damage your gauge. If you do overload the gauge, the display will flash with “0000” or “_ _ _ _”. If your gauge displays “-EP”

“-EPP” or “-EL”, contact your AMETEK or CHATILLON representative for service.

MAINTENANCE & CALIBRATION

You should routinely check and verify gauge accuracy by suspending a known weight from a hook adapter. If calibration is required, please contact AMETEK or your local AMETEK representative.

To maintain optimum performance, we recommend a factory calibration every 12 months.

- WARNING -

This force gauge is equipped with a rechargeable battery. The battery is recyclable. It may be unlawful to dispose of this battery into the municipal waste stream. Please check with yor local solid waste officials for details on how to properly dispose of the battery.
