Start Up
Before you use the TLS 216 Logic Scope, ensure that it is properly installed and
powered on.
Before You Begin
To ensure maximum accuracy for your most critical measurements, you should
know about signal path compensation.
Be sure you compensate your logic scope for the surrounding temperature. This
action, called Signal Path Compensation (SPC), ensures maximum possible
accuracy for your most critical measurements. See Doing a Signal Path
Compensation on page 3–53 for a description of use and operation of this
feature.
Operation
To properly install and power on the logic scope, do the following tasks.
1. Be sure you have the appropriate operating environment. Specifications for
temperature, relative humidity, altitude, vibrations, and emissions are
included in the manual TLS 216 Performance Verification and Specification
shipped with this logic scope.
2. Leave space for cooling. Do this task by verifying that the air intake and
exhaust holes on the sides of the cabinet (where the fan operates) are free of
any airflow obstructions. Leave at least 5.1 cm (2 inches) free on each side.
WARNING. To avoid electrical shock, be sure that the power cord is disconnected
before checking the fuse.
3. Check the fuse to be sure it is the proper type and rating (stated on rear
panel). You can use either of two fuses. (See Figure 1-1 for fuse location.)
Each fuse requires its own cap. (See Table 1–1.) The logic scope is shipped
with the UL approved fuse installed.
4. Check that you have the proper electrical connections. The logic scope
requires 90 to 250 VAC
RMS
, continuous range, 47 Hz to 63 Hz, and may
require up to 300 W.
