This instrument provides a special output switch, the output voltage can be preset as required
before the switch is unpressed. After the voltage is adjusted, press the switch. This switch is
an uncontacted electricity type of switch so it does not generate a mechanical spark,
protecting users’ safety.

Model TY– 43 digital meter adopts LED digital tube as display unit. At least, one or two
digits generated by the display may flicker. It is not caused by the wareform or noise of
output, while by characteristics of the A/D convertor.
When there is no input voltage, the display will be recovered to zero automatically. When the
input voltage, is inverse, “-” polarity will be displayed automatically. When the operating
voltage is 5V, its input sensitivity is DC
±
199.9mV of full-scale.

The instrument is designed symmetrically between left and right on the front panel. On the
upper side, there are two digital meters. A switch for output in the middle of the panel is
mounted. There are four knobs in line as voltage potentiometer of each circuit, and current
setting potentiometers for each way. The two external sockets are mounted in the middle or
lower part of the panel and at the bottom of the panel there are a pair of output binding posts
and a screw grounded with a short bar. When “+” or “-” to ground is needed, we can connect
the short bar.
At the lowest bottom of the instrument’s back, there are one power cord and two pairs of
input sockets for the remote-control signal corresponding to the two ways on the front panel.
There are L/R (local/remote control) and V/C (voltage/current control) operating selector
switches, respectively. The input fuses both are mounted on the rear panel of the instrument.
