Procedures
Introduction
This chapter provides instructions for routine maintenance that may be
required for your REMOTE 2012, 3012, 5012, 3102 or 5102
instrument.
The maintenance procedures described in this chapter are not required
on regular or prescribed intervals and should be performed only if you
have reason to question the data you are receiving from the instrument.
Safety
Before performing any of the maintenance tasks described in this
chapter, read Chapter 1 of this manual and become familiar with the
warnings and caution labels.
Calibration
To maintain optimum performance of this instrument, it should be re-
calibrated annually by a Lighthouse Authorized Service Provider.
Purge Count
Test
This section will provide you with the procedure to check the counter
for zero counts. A purge filter must be attached to the instrument and
six (6) five (5) minute samples must be taken. There should be no more
than 1 count on average per five-minute sample.
1. Disconnect power from the instrument.
2. Connect the Purge filter to the sample inlet.
3. Apply power to the instrument.
4. Configure the unit to run one 30-minute sample.
5. Run the 30-minute sample. This time allows the unit to warm up
and purge any residual particles that might be inside the
instrument.
6. Stop sampling.
