PT2026 Installation and Safety Manual
BASICS

6- Maintenance and Service

 Do not remove covers. Refer servicing to qualified personnel. The contact
information for Metrolab can be found in Section 1-3.

6-1 CALIBRATION

Recalibrating a PT2026 consists of adjusting its internal reference clock, a
procedure only to be performed at the Metrolab factory. However, any properly
equipped calibration laboratory can certify the calibration by measuring the
internal 10 MHz reference clock output on the back panel. In addition, if you use
an external 10 MHz reference clock, the PT2026 does not need to be calibrated at
all.
All customers are of course free to fix the intervals at which they check the
calibration of their instruments, within the context of their quality assurance policy.
Metrolab's recommendation is to check the PT2026 calibration once every year.

6-2 UPGRADES

Metrolab makes improvements and bug fixes for the PT2026 firmware, software
and manual available via its website. The Download page of the Metrolab website
(see Section 1-3) will always contain the latest versions.
The PT2026 Main Unit is designed such that you can upgrade the firmware in the
field. Firmware upgrades are a delicate procedure, as a failure may render the
instrument unusable. Metrolab has made every effort to make the process
foolproof, but please take your time and follow the instructions provided with the
upgrade carefully.
The PT2026 peripherals (probes, multiplexers, etc.) also contain firmware.
However, at this time, this firmware cannot be upgraded in the field; peripherals
need to be sent back to the factory to be upgraded.

6-3 TROUBLESHOOTING

Many problems can be diagnosed over the phone or via e-mail. Should you have
trouble with your PT2026, you should first contact your local representative.
