– Connections for cell voltages > 10 V
The input range of the Autolab differential amplifier is limited to 10 V. When the
cell voltage is larger than 10 V, for example when measuring on large cell stacks,
the input voltage of the Autolab can be extended to 100 V by using the Voltage
multiplier (Item code: VOLT.MULT).
7.2.1
– Voltage multiplier part list
The Voltage Multiplier kit includes the following items:
1.
The Voltage Multiplier box (see Figure 10)
2.
A red 30 cm long male banana to banana cable
3.
A blue 30 cm long male banana to banana cable
Note
It is recommended to connect the RE and S leads from the PGSTAT as close as
possible to the cell.
Important restriction
The Voltage Multiplier reduces the input impedance of the PGSTAT
electrometer to ~ 100 kOhm. Only use the Voltage Multiplier when the total
impedance of the DUT is very low with respect to the input impedance
(typically, 100 Ohm or less).
