User manual HANNA INSTRUMENTS HI 931001

[. . . ] These instruments are in compliance with the directives EN 50081-1 and EN 50082-1. PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipment. Each pH/mV simulator is supplied complete with: · HI 7858/1 BNC/BNC Coaxial Cable; Note: Save all packing material until the instrument has been observed to function correctly because all defective items must be returned to the Dealer in their original packing. TABLE OF CONTENTS Preliminary Examination . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 GENERAL DESCRIPTION HI 8427 and HI 931001 are portable pH/mV simulators designed specifically for calibrating pH and mV (ORP) meters. [. . . ] pH 4 at 30°C). pH7 HI 931001: · Connect the simulator to the pH meter using the HI 7858/1 cable provided. · Manually set the temperature compensation of your meter to 25°C. · Switch the simulator on and select the pH mode by pressing the RANGE key. pH pH HI 8424 microcomputer pHmeter ON OFF HI 931001 pH/mV Calibrator SETTING ON OFF RANGE pH HI 8427 pH/mV CALIBRATOR · 0 10 20 30 Make sure that the two additional decimal points are not displayed. If they are displayed, change the battery of the simulator before performing the calibration. Turn the Coarse and Fine knob to set any desired pH value and make sure that the pH meter you are checking reflects the correct result (e. g. 7. 01 pH). · 50 40 °C · · If your pH meter has a temperature probe connected to it, set the °C knob to the measured temperature displayed by your pH meter. If your meter is manually compensated for temperature, adjust the temperature settings for both the pH meter and the simulator to the same temperature. Verify that the pH meter displays the correct pH value compensated at the 6 · If not, adjust the pH meter until the correct reading is displayed (refer to the pH meter instruction manual). pH pH HI 8424 microcomputer pHmeter ON OFF HI 931001 pH/mV Calibrator SETTING 7 mV (ORP) CALIBRATION · HI 8427: · Connect the simulator to the mV (ORP) meter using the HI 7858/1 cable provided. · · pH HI 8427 pH/mV CALIBRATOR Switch the mV meter on and select the desired mV value on the simulator. If it is lit, change the bat-350 tery of the simulator bemV fore performing the calibration. · If the meter is not displaying the correct mV value, adjust the meter until it displays the correct mV (refer to the mV meter instructions manual). Note: The °C knob is not effective during mV calibration. Make sure that the the two additional decimal points are not displayed. If they are displayed, change the battery of the simulator before performing the calibration. Turn the Coarse or Fine knob to any desired value and make sure that the mV meter you are checking reflects the correct result. · If not, adjust the mV meter until the correct reading is displayed (refer to the mV meter instruction manual). mV mV HI 8424 microcomputer pHmeter ON OFF HI 931001 pH/mV Calibrator SETTING Note: Temperature compensation does not apply here. HI 931001: · Connect the simulator to the mV (ORP) meter using the HI 7858/1 cable provided. pH pH HI 8424 microcomputer pHmeter ON OFF HI 931001 pH/mV Calibrator SETTING ON · Switch the simulator on and select the mV mode by pressing the RANGE key. OFF RANGE 8 9 CABLE HIGH IMPEDANCE TEST pH VALUES AT VARIOUS TEMPERATURE HI 8427 only: Temperature has an effect on pH. The calibration buffer solutions are effected by temperature changes to a lesser degree than normal solutions (see table below). Note: With HI 8427 your pH meter will always show the pH buffer solution at the standard temperature of 25ºC. · Connect the simulator to the cable (e. g. HI 7855). · Press the HIGH IMPEDANCE key and observe the LEAKAGE LED while you are turning the simulator rotary knob to any pH/mV value. HIGH IMPEDANCE · If the LED does not light, the cable and connector going to the meter are in perfect condition. If the LED is lit, it means there is a leakage problem with the cable and connector and you should check/replace it.
