6.5  Operation in <MAINT.> Mode

This section describes key operations by specifying the functions in the <MAINT.> mode and 

describes the operations in the following order.
(1)  Zero calibration (with zero water)
(2)  Zero calibration (with lamp turned off)
(3)  Zero-shift calibration (Zero-point correction)
(4)  Span calibration (with standard solution or calibration plate)

(5)  Span calibration (sensitivity correction)
(6)  Manual start of automatic cleaning
(7)  Manual start of automatic calibration
(8)  Reference sensitivity calibration

(9)  Converter check operation

(10)  Error code display
(11)  Error resetting
(12)  Reference lamp control value calibration

(13)  Version number display
(14)  Password entry to switch to the adjustment mode

(1)  Zero Calibration (with "zero water") [FUNCTION "1"]

The zero-calibration operation using "zero water". For the value operating procedures, see 

Section 7.6.

The following is a description of the key operations.

 

 

 

(Example of display)

(1)  Select FUNCTION "1" in the <MAINT.> mode. 

=>  000.04 mg/L

(2)  Press the [ENT] key after the display becomes   =>  The "CAL" lamp begins to flash.

 stable.

(3)  Press the [>] key. 

=>  000.00 mg/L is displayed.

(4)  Press the [ENT] key to terminate calibration. 

=>  000.00 mg/L

The entire display flashes once and the "CAL" lamp goes out.
In addition, at operation 4, the measured signal at the zero point is checked and if the permissible 

range (-10 to 10 mV) is exceeded, Err21 (zero calibration overrange) is displayed (see Section 

5.3 *3). In this case, the "FAIL" lamp is not lit and a FAIL contact is not output.
An error message can be reset by pressing the [ENT] key and the display returns to the turbidity 

indication. Wait until the display becomes stable and then begin from step 2 again.

At any stage of zero-calibration operation, pressing the [MODE] key or [FUNC] key allows 

switching to another mode or function. Calibration computation is not performed unless the 

operation of 4 is carried out.

Note:  At this calibration, the turbidity not multiplied by the correction factor from the zero-shift calibration (zero correction) in (3) or span 

calibration (sensitivity correction) in (5) is displayed.

(2)  Zero Calibration (with lamp turned off) (FUNCTION "2")

The zero-calibration operation is done by automatically turning off the lamp. Only in a measured 

turbidity exceeding 200 mg/L, can zero calibration be performed simply in the following 

operations. A turbidity reading with the lamp turned off reads a value 1 mg/L smaller than a 

reading using "zero water".
