WARNING!
BEFORE OPERATING THIS OR ANY OTHER TEST EQUIPMENT
READ ALL SAFETY WARNINGS AND UNDERSTAND THEM FULLY.
DO NOT VARY INPUT VOLTAGE (MAINS) AFTER POWERING ON
TEST SET.
The TR-Mark III 250V auto-senses the input (mains) voltage from 100
to 250 vac 50 / 60 Hz.
The TR-Mark III 250V then “locks–in” the test voltage range. If the
input voltage (mains) is varied after the TR-Mark III 250V was powered
on the actual test voltage may be higher or lower than indicated.
