Although the CON 510 bench meter has an automatic ranging capability, you may also
manually select any specific measurement range you wish to work on by pressing
RANGE each time for every range.

(if TDS factor is 0.5)
r 1 0 – 20.00 µS/cm 0 – 10.00 ppm
r 2 0 – 200.0 µS/cm 0 – 100.0 ppm
r 3 0 – 2000 µS/cm 0 – 1000 ppm
r 4 0 – 20.00 mS/cm 0 – 10.00 ppt
r 5 0 – 200.0 mS/cm 0 – 100 ppt
1. To manually select the desired measuring range, press RANGE key while you are
in the measurement mode. The first range will appear on the display and the
[MEAS] indicator blinks.
2. Press RANGE key again (if needed) until the desired range is selected.
3. To re-select the Auto-ranging function, repeatedly press RANGE key until the
[MEAS] indicator appears without blinking. The display will then scroll through the
various ranges and the Auto-ranging function resumes. Or simply power off and on
again will restart meter into Auto-ranging function as default.
NOTES: If the value of the solution you are measuring is higher than the range
selected, an error message code “Or” will appear on the upper display indicating an
over-range condition. Press RANGE key until the correct range is selected. However the
meter reverts back to the Auto-ranging function once it is powered off.
5.5 HOLD Function
This feature allows you to freeze the displayed reading momentarily when activated in
the measurement mode and the [HOLD] indicator appears on the LCD. To release the
held value, press HOLD again and the [HOLD] indicator disappears. You may continue
to take measurements.
