A-3 Setup for Preparation and Use
The following quick-step guide can be taken to power up and use the AMPTEC 620LK
meter:
1) The meter may be set up to operate as soon as the power is turned on, which
can be accomplished by pressing and holding down the power switch for 2
seconds.
2) Connect the unit’s chassis ground panel jack on the front panel to a local earth or
ground connection.
3) Check the product’s display for a low battery indication. If the product has a low
battery, the display will say “LO BAT”. To see instructions on battery
replacement, see section E-9.1 on page 17.
4) Perform a visual test lead integrity check. It is recommended that the user
perform a basic visual inspection of their test lead set to confirm there is no
damage to any portion of the set.
5) Perform a multimeter continuity test of your test lead set. To do so, ensure all
four wires are isolated from each other, and then connect each pin to its
corresponding opposite pin. Many multimeters will simply beep to indicate that
the leads you are testing are operational.
For a more detailed instructional information on how to use the 620LK meter, see
section D-4 on page 11.
The 620LK meter may be used in any area where the environment does not exceed the
specifications listed in section B on page 5. When possible, avoid exposing the meter to
extremes of temperature, which will affect accuracy and shorten battery life. One should
become familiar with the basic test lead usage and the autolock feature described in
detail in this manual in Section D-2.4 on page 9 in order to properly use the unit.
