2 initial inspection carefully unpack the instrument and accessories. Inspect for damages made in shipment. If any damage is found, notify your jenco representative immediately. All packing materials should be saved until satisfactory operation is confirmed. General introduction the model 6173 is a ...
The model 6173 uses ph and orp electrodes with bnc connectors and interchangeable atc ( automatic temperature compensation ) / temperature probes. Other features include electrode offset recognition, electrode slope recognition, electrode efficiency display, built in buffer coefficients, automatic o...
Turning on/off the instrument when the instrument is not in use, press the on/off key to turn off the instrument. Unplugging the ac adaptor from the instrument or from the ac line does not turn off the instrument. It would automatically switch to the internal batteries. The instrument will continue ...

8 1. Calibration with an atc/temp probe in the ph-autolock mode. 1.1 connect the ph electrode to the bnc connector and the atc/temp probe to the atc/temp connector of the instrument. The atc annunciator on the lcd will be on. Press the [mode] key if necessary to go to ph-autolock mode. 1.2 rinse the...
9 locked to the second buffer value corresponding to the temperature of the second buffer. When a stable reading is reached, the wait annunciator will stop flashing and stay off. The instrument will calculate and compensate for the ph electrode slope deviation corresponding to the values of the two ...
10 completed and the instrument is ready to be sloped at a second buffer. Allow sufficient time for the electrode and atc/temp probe to stabilize before taking any action. 2.4 remove the ph electrode from buffer 7.00 (or 6.86), rinse with distilled water and immerse it in buffer 4.00(4.01) or 9.18(1...
11 probe to stabilize. Press the [stand] key. The stand annunciator will be on and the slope annunciator will flash, indicating that standardization at buffer 7.00 (6.86) is completed and the instrument is ready to be sloped at a second buffer. The instrument will display the buffer value correspond...
12 instrument. The man annunciator will be on. Press the [mode] key for the lcd to indicate ph and for the auto annunciator to be off. 4.2 rinse the ph electrode in distilled water and immerse in buffer 7.00(6.86). Set the instrument to display the temperature of the buffer by pressing the [ ∆ ] and...
13 of the two calibration buffers. The instrument is now dual point calibrated and ready for measurements. After two point calibration, pressing and holding the [mea./eff.] key for about 5 seconds will display the new electrode efficiency. Ph measurements the stand and slope annunciators must be on....
14 1.5 for samples that are inherently unstable, the instrument will not autolock. In this case, use the ph non-autolock mode for measurements. 2. Measurement with atc/temp probe in the ph non-autolock mode. 2.1 connect the ph electrode and the atc/temp probe to the connector of the instrument. The ...
15 display changes less than 0.01 ph within approximately 10 seconds, the autolock function will be activated. The wait annunciator will stop flashing and stay off. The reading is then locked and will not respond to further changes from the ph electrode. 3.5 for samples that are inherently unstable,...
16 disappear and the correct temperature reading will be displayed. It is not necessary to press the [clear] key. Mv measurements 1. Measurement in the mv-autolock mode. 1.1 connect the optional combination orp electrode to the bnc connector of instrument. 1.2 press the [mode] key for the lcd to ind...
