PRELIMINARY EXAMINATION
HI 4211 and HI 4212 are professional bench meters with graphic LCD for pH, ORP (Oxidation Reduction
Potential), ISE (HI 4212 only) and Temperature measurements with Calibration Check.
The display can be configured as a single channel or dual channel display (HI 4212 only) in various modes: Basic
information only, GLP information, Graph mode and Log History mode. Each channel can be configured as pH, mV,
Relative mV or ISE (HI 4212 only).
The main features of the instruments are:
• One (HI 4211), or two (HI 4212) input channels;
• Manual selection, automatic and semiautomatic pH calibration up to five points, with standard (1.68, 3.00,
4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) and custom buffers (up to 5 custom buffers);
• Manual Selection and Custom Standard ISE calibration up to five points, with standard (up to five standard
solutions for each measurement unit) and custom solutions (up to 5 custom solutions), with or without
temperature compensation;
• AutoHold feature to freeze first stable reading on the LCD;
• Two selectable alarm limits;
• Five selectable logging modes: Automatic logging with and without AutoHold feature, Manual logging with
or without AutoHold and AutoHold logging mode;
• Up to 100 logging lots;
• Selectable log interval and log sampling features for Automatic logging;
• GLP feature;
• Online and offline graph;
• User-friendly interface on large B/W graphic LCD (320x240 pixels);
• PC interface via RS232, and USB.

POWER CONNECTION
Plug the 12 VDC adapter into the power supply socket.
Notes: • These instruments use non volatile memory to retain the pH, Ion calibrations and all other
settings, even when unplugged.
• Make sure a fuse protects the main line.
ELECTRODE AND PROBE CONNECTIONS
For pH or ORP measurements connect a pH/ORP electrode with internal reference to the BNC connector
located on the rear panel of the instrument (for the desired channel – HI 4212 only).
For ISE measurements (HI 4212 only) connect, to the desired channel, an ISE electrode with internal
reference to the BNC connector located on the rear panel of the instrument.
For electrodes with a separate reference connect the electrode’s BNC to the BNC connector and the electrode’s
reference to the reference input socket.
For temperature measurements and automatic temperature compensation connect the temperature probe to the
appropriate socket (for the desired channel – HI 4212 only).
INSTRUMENT START UP
• Turn the instrument on from the power switch located on the rear panel of the instrument.
• Please wait until the instrument finishes the initialization process.
Note: It is normal for the loading process to take a few seconds. If the instrument doesn’t display the next
screen, restart the meter using the power switch. If the problem persists, contact your dealer.
