Rear panel multiplexer function (only for the model with multiplexer module) 
 
Including the model with multiplexer card, the voltage limit of LO relative to safe ground 
falls to 200Vpeak (Max). 
  
Channel: 12 voltage, 4 current, additional protections. 
Measurement Type:2-Wire resistance; Capacitance; DC Voltage; DC Current; AC Voltage; AC 
Current; period; Diode and Frequency. 
Work Characteristics:The precision of performance and front panel measurement is the same. 
The switch time of multiplexer card is 50ms; the switch time of auto measurement is 600ms (4½ ). 
Input Characteristic: different input voltage is 150Vpeak(Max); the isolated voltage between the 
channels is 150Vpeak(Max),the current end is input 1Apeak(Max), channel isolation > 60dB 
(@10KHz),the voltage of all the ends relative to safe ground is 150Vpeak(Max). 
Input Protection: 2A restore the fuse in current channel, 250V limit voltage. 
 500mA melt the fuse in voltage channel with multiplexer card.
