Operation                                                               

The most commonly used features, such as displaying force, peak hold, zero and changing of displayed units of
measurement can all be done by pressing a single dedicated key on the front panel - see page 6, Basic Functions.

 

Powering the Gauge

The CFG+ is supplied with a set of 4 x 1.5V AA batteries. To fit the batteries you must first remove the battery
cover on the upper part of the rear of the gauge. To release the battery cover press the battery cover as indicated
by the arrow and slide the cover upwards. Fit the batteries in the battery holder ensuring that you observe
polarity. Incorrect insertion of batteries can cause damage to the gauge.

To replace the battery cover slide it from the top edge of the gauge until it clicks into place.

If the gauge is not going to be used for 3 months or more the batteries should be removed and stored separately.
(Settings and calibration data will not be lost if the batteries are removed).

 

Replacing batteries - Low battery symbol

If the low battery symbol appears on the display the gauge will power-off unconditionally at intervals of one
minute. The gauge may be repowered but will power-off every one minute as long as the low battery symbol
remains on the display.

This feature has been designed into the gauge to protect the integrity of displayed readings because when the
low battery symbol appears the accuracy of the loadcell reading may be compromised.

When the low battery symbol appears on the display, fit four new 1.5V AA batteries in the gauge.

Rechargeable batteries should not be used in the CFG+.

Rechargeable batteries should not be used in the CFG+.

 

Mains operation

The CFG+ can also be powered directly from the mains using an AC Power Adaptor plugged into the right hand
side of the gauge (available as an optional extra). Using an incorrect power adaptor can damage the gauge.

 

Battery safety information

NEVER:

NEVER:

Short circuit                            
Heat or incinerate
Disassemble or deform cells
Immerse in water
Solder anything to the battery terminals Reverse individual cell polarity                   
Use alternative chargers other than that supplied by Mecmesin (Available as an optional extra)
Use replacement parts other than that supplied by Mecmesin

Never dispose of batteries with ‘normal’ refuse. Contact your local Environmental Authority to determine the
location of your appropriate disposal facility.

 

Using the Gauge 

Fitting accessories

All CFG+ instruments are supplied with a short extension rod (30mm long). This fits directly onto the loadcell
mounted in the bottom of the CFG+.

Note: 

Note: 

When fitting the extension rod always ensure that it is screwed finger-tight only. Excessive torque or

overtightening can damage the loadcell.

Note: 

Note: 

When attaching accessories to the gauge always use the extension rod.
