Password Setting - Toshiba LF620 Instruction Manual

Note 1: If you try to set a value outside of the range, 2.4mA or 24mA (in the case of fixed current
output) or 10000pps (in the case of fixed pulse output) will be forcibly set.
Note 2: The pulse width set in Section 8.2.20 is used for fixed pulse output. The pulse width must not
be greater than 40% of the period of the fixed output set frequency. However, if the setting
exceeds 1000pps, the pulse width automatically will be set to 40% of the period of the fixed
output set frequency.
Note 3: If the fixed output is set to ON, the screen automatically changes to the fixed output current
value and fixed output pulse value setting screen. However, the fixed output actually starts
when the fixed output pulse value setting is completed. (If the fixed output current value or
fixed output pulse value is set independently, the fixed output starts when either of the setting
is completed.)
