7. Recorder Output Option
This section is applicable when the optional analogue recorder output is fitted.
The recorder output corresponds to the currently selected display mode. There is
no output in RS232 Send Rate or RS232 Baud Rate modes.
The output voltages are as follows:
pH
: 0 to 14.00 pH for 0 to 2000 mV
i.e. pH7.00 = 1000 mV Output
mV
: -1500 to +1500 mV for 0 to 2000 mV
i.e. 0 mV Reading = 1000 mV Output
Temperature : -10.0 to 120.0
O
C for 0 to 2000 mV
i.e. 0.0
O
C = 152 mV Output
Output impedance approx 1000 Ohms.
