Troubleshooting

No Power To Instrument

There are two common causes for the unit to not power

up when the POWER switch is pressed for three sec-

onds.

The most common is that the batteries are dead. Try

replacing the batteries with new alkaline batteries or try

powering the unit from the AC power adapater.

The second most frequent cause for no power to the

instrument is a blown protective fuse. This fuse can be

shorted out if the batteries have been removed from

the instrument with a metallic object such as a

screwdriver. If the protective fuse has been blown

contact the factory.

"Battery is low!"

accompanied by an audible beep.

If battery power drops below 5% capacity, the screen will

flash "Battery is low!". Replace the batteries or switch to

AC power.

"Flow too low" / "Flow too high"

audible beep.

Accurate air flow is critical to an accurate gas mixture.

The microprocessor and built-in precision mass flow

sensor continuously monitor the air flow. If, however, a

flow problem develops (e.g. air blockage or kinked

tubing) which cannot be corrected within ten seconds,

the unit will display "Flow too low." If the problem cannot

be cleared after an additional minute, the instrument will

enter the purge mode and then power down.

Optional items available for the Cal 2000 LT include:

AC Adapter

The Cal 2000 LT may also be operated from an AC adapter.

The AC adapter converts the AC voltage supplied from the

main power lines to 6 VDC which is used in lieu of the bat-

teries. The adapter plugs into the instrument from the un-

derside of the case directly into the power board and is in-

dependent of polarity.

If needed, contact the factory for

exact specifications of the AC adapter.

Hard Body Instrument Case

A water resistant, padded instrument case is available for

storage and shipping of the Cal 2000 LT. The case is

made out of rugged, high impact resistant plastic and will

help protect the instrument in harsh environments. The

foam insert may be customized to hold additional items

like spare batteries and cells.

Extension Hoses

Longer sample hoses may be purchased for use with the

Cal 2000 LT in lengths up to 20 feet. Note: the internal

pump may not be capable of overcomming flow restricions

associated with extreme hose lengths when operating at

1.0 LPM.
