Getting Started
Unpacking and Repacking
Remove the calibration certificate and place it in a secure location. Remove
the instrument and ensure that all of the items listed on the packing list are
in the carton. Check individual item serial numbers and ensure calibration
certificates match. The Model 240 serial number is located on a label on the
front of the unit.
To return an instrument for repair or calibration, provide sufficient packing
material to prevent damage during shipment. Every returned instrument
must be accompanied by an Instrument Return Form , which can be
downloaded from the Ludlum website at www.ludlums.com . Find the form
by clicking the “Support” tab and selecting “Repair and Calibration” from
the drop-down menu. Then choose the appropriate Repair and Calibration
division where you will find a link to the form.
Gas Bottle Installation
When using the gas proportional version of the Model 240, you will
need to use a bottle of P-10 gas (not included). As given in the
Specifications section, the maximum gas bottle size is 22.9 cm (9 in.)
diameter by 66 cm (26 in.) tall. The following is the procedure to install
the gas bottle.
1. The instrument typically comes with a regulator, a valve, a brass
fitting, two white plastic compression nuts, and some vinyl tubing.
The valve is in the box with the regulator. The other parts may be in
a separate bag.
2. Screw the valve into the output of the regulator. If there is an arrow
on the valve, it should point away from the regulator. Screw the
fitting onto the valve. Use Teflon tape or sealant on the connections.
3. Set the gas bottle onto the cart and secure with the provided strap.
To adjust the strap, open the buckle completely, extend or retract
the strap through the latch as necessary, then close the buckle.
Attach the regulator onto the bottle.
