Limits Display	With the dc output switch set to Off, both meters show the set values (i.e. the limits). With the output On, either the voltage meter or current meter will show a measured value (depending on the CV/CI mode). Pressing the Limits button will provide a temporary display of the set values.

QL355T 英國tti直流電源,英國tti QL355T：

ALARM OUTPUT
Isolated rear-panel open-collector output signal. User can select output to be activated for either OVP, OCP, Overtemperature or Sense miswiring, or for any of those four faults.

link & COPY

(Triple Output Models) Each output can be controlled independently or can be linked. When linked, keyboard and jog wheel control operates on both outputs simultaneously. linked mode can be used to create tracking outputs, or for convenient series or parallel operation of the two outputs. A Copy function is available which copies all of the settings for output 1 to output 2 (Range, Set volts, Set current, OVP, OCP). linked mode can also be used to store the settings for both outputs to a group of common memory stores when simultaneous recall is required. (Note: linked mode can be selected with differing voltage and current settings on the two outputs. However both outputs must be set to the same range.)
