Set Upper Limit Control
Adjust this control to the Millivolt value at which the High LED and
relay output are activated. Factory-set to activate when the reading is
above the Upper Limit. See section 3.5.
High LED
The High LED provides visual indication of when the Upper Limit has
been exceeded. Factory-set to light up when the reading is above the
Upper Limit. See section 3.5.
Set Lower Limit Control
Adjust this control to the Millivolt value at which the Low LED and
relay output are activated. Factory-set to activate when the reading is
below the Lower Limit. See section 3.5.
Low LED
The Low LED provides visual indication of when the Lower Limit has
been exceeded. Factory-set to light up when the reading is below the
Lower Limit. See section 3.5.
Zero Calibrate Control
Adjust this control to calibrate the proCHEM-R in a Redox standard.
See section 4.
Span Calibrate Control
This control is not required for the proCHEM-R.
Function Switch
The Function Switch is used to select the mode of operation. See
section 2.
Display Window
The proCHEM-R has a large, easy to read LCD display. The units of
measurement are clearly shown in the window beneath the display.
Terminal Cover
6
The terminal cover provides easy access to all of the connections,
relay output fuses, configuration jumpers and user-adjustable
trimmers. The cover is water resistant to IP65.

2. Operating Modes
The function switch is used to select the required mode. The four
operating modes available are…
1. Set Upper Limit : Switch to Set Upper
Limit when setting the Millivolt value at which
the High LED and relay output are activated.
The relay output is not operational in this mode.
Factory-set to activate when the reading is
above the Upper Limit. Can be user set to be a
activate when the reading is below the Upper
Limit. See section 3.5.
2. Set Lower Limit : Switch to Set Lower
Limit when setting the Millivolt value at which
the Low LED and relay output are activated.
The relay output is not operational in this mode.
Factory-set to activate when the reading is
below the Lower Limit. Can be user set to be a
activate when the reading is above the Lower
Limit. See section 3.5.
3. Calibrate : Switch to Calibrate mode to
place the proCHEM-R into standby (eg. when
calibrating). This mode disables the two output
relays to avoid chemicals being added when
placing the sensor into calibration buffers.
4. Automatic Control : Switch to
Automatic Control to enable the Alarm LED’s
and relay outputs. These will be activated when
the Millivolt reading is outside the Upper and
Lower limit values. See section 3.5.
