5.1.2 Temperature Accuracy

Preparation
• Use (T) and (K) temperature compensation leads to connect a 0˚C reference temperature device (zero
controller) to the GL200A input terminals as shown below.
• As shown below, use copper leads to connect the 0˚C reference temperature device (zero controller) to a
voltage generator that can specify output up to 1µV.
Wiring connection
Voltage generator
0.00000 V
FG
Connect the GND terminals.
AC adapter
Note : The compensation leads should be connected individually. Do not connect in parallel. Connect the
FG of the voltage generator and the AC adapter.
