ANALOG OUTPUT
All models pH 500XY1 and mV 600XY1 are provided with the
analog output feature.
The output is isolated and can be a voltage or a current.
With the recorder, simply connect the
common port to the ground output
and the second port to the current
output or voltage output (depending
on which parameter is being used)
as depicted aside.
The type (voltage or current) and the range of the output
analog signal is selectable through the jumpers on the
power board.
Configurations of the switch are as follows:
Output Switch 1 Switch 2 Switch 3 Switch 4
0-5 VDC, 1-5 VDC OFF ON – – – –
0-10 VDC ON OFF – –
0-20 mA, 4-20 mA – – – – ON
0-1 mA – – – – OFF – –
Choice between different ranges with the same configura-
tion (for example 0-20 mA and 4-20 mA) is achieved via
software by entering the setup mode and selecting code
40 (see Setup Mode section for exact procedure).
Factory default is switches 1 and 3 closed (ON) and switches
2 and 4 open (OFF), i.e. 0-20 mA, 4-20 mA, and 0-10
VDC.
In any case, contact the nearest Hanna Customer Service
Center for changing of the default configuration.
By default the minimum and maximum values of analog
output correspond to the minimum and maximum of the
range of the meter. For example, for the pH 500 series
with a selected analog output of 4-20 mA, the default val-
ues are 0.00 and 14.00 pH corresponding to 4 and
20 mA, respectively.
