Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any damage, notify your dealer.
Each meter is supplied complete with:
• HI 76303 conductivity probe
• HI 3316D resistivity probe
• 12 Vdc adapter
• Instruction manual
Note: Save all packing material until you are sure that the instrument
functions correctly. All defective items must be returned in the
original packing with the supplied accessories.
GENERAL DESCRIPTION
HI 216 is a combination bench meter that can read conductivity in 4
different ranges, and resistivity.
For conductivity measurements, the calibration is a simple 1 point
procedure through the easy-to-operate front panel knob, and the
supplied probe does not require re-calibration when switching from
one range to another.
The 4-platinum-ring probe has a built-in temperature sensor that
automatically compensates for temperature changes, and the temperature coefficient can be adjusted from 0 to 2.5% through a knob
on the front panel.
For resistivity measurements, the meter is factory calibrated and, if
necessary, calibration can be adjusted by acting on the trimmer
located on the rear panel.
The HI 3316D resistivity probe is easy to clean and requires little
maintenance. It also features a built-in temperature sensor to
automatically compensate for temperature variations, with an userselectable (from 2 to more than 7%) temperature coefficient.
Both probes use the same DIN plug on the rear panel, and the meter
automatically recognizes which probe is connected.
