Dual 4-digit meters, 10mm (0·39") LED.
Resolution 10mV
Accuracy ± (0·1% of reading + 10mV)
Resolution 1mA; 0·1mA on 500mA range.
Accuracy ± (0·3% + 3mA) to 3A, ± (0·5% + 3mA) to 6A;
± (0·3% + 0·3mA) on 500mA range.
Selects a 2s time constant (normally 20ms) for averaging of rapidly
varying load currents.
Each output is fully independent and isolated. Operation is equivalent to
two single power supplies.
The two outputs remain isolated but the Slave voltage controls are
disabled and the Slave voltage is set equal to the Master voltage.
Slave voltage = ±(0.1% of Master voltage setting +10mV).
As tracking but the Slave voltage controls set an output voltage between
0% and 101% of the Master voltage. Once set, varying the Master voltage
will create the same percentage change in the Slave voltage setting.
% change in Slave voltage = % change of Master voltage ± 0.1% ±10mV).
The Master output operates as a single output power supply with twice the
current capability (0.2mA to 6A). The Slave is disabled (its displays are
both off).
Each output has an independent DC On/Off control; these additional keys
can be used to turn both outputs on or off simultaneously. These keys
operate in all four modes.
