28 Instruction 55-9002

Maintenance

Batteries

The battery voltage is monitored by the instrument’s microprocessor, and

can be checked by momentarily pressing the key. Refer back to the

previous section Battery Voltage Check.

Battery replacement is recommended when the voltage at startup is less

than 2 volts. The batteries must be replaced when the display starts

blinking every five seconds while showing “b” in the RANGE window.

To replace the batteries, refer back to the previous section Battery

Installation.

Sampling Probe

The sampling probe is the most likely candidate for maintenance as it is

subject to damage in normal field operations. The probe tube may be

made of either aluminum or clear polycarbonate.

Replacing either probe is a simple matter of unscrewing the damaged

probe and installing a new one. Replace the O-ring if it looks deformed

and can no longer provide an air-tight seal. See Figure 22.
