nected to the ‘zero’ output tap of the power transformer. Measure-
ment range switching is automatic.
Auxiliary Voltage Supply
By means of a transformer with multiple secondary windings, the PTE-100-C
PRO features two independent auxiliary voltage outputs:
• Out 3 is a variable 0-250 VDC stabilized, electronically protected
supply with a dedicated ON/OFF switch, and
• Out 4 is a fixed 110 VAC. This fuse-protected output is permanent-
ly active whenever the equipment is switched on.
Measurement and Control
Analogue input is converted to digital values before it is processed and dis-
played. The following external or internal analogue magnitudes are meas-
ured:
• Voltage.
• Current.
• Phase angle.
• Temperature.
Displayed and/or used values like Impedance or Power are automatically
calculated from these magnitudes by the microcontroller.
