## .. ØMEAS ..... U.standby ........mV

Function Switch off voltage, current and DME.

Parameter Range; Default value / Meaning

U.standby -3000...3000 mV; -

Standby voltage after measurement

The voltage entered here is applied to the electrodes. This voltage

remains in force even after the end of the main program on the

"OP.SEQUENCE" page. It is switched off only by a new ØMEAS instruc-

tion with U.standby = empty, by a MEAS instruction or by the new start

of a method.

The standby voltage U.standby is displayed on the "STAND" page.

If the voltage applied to the electrodes should be switched off,

U.standby must be empty (press <CLEAR> to empty the contents of

the field).

Description The ØMEAS instruction is used to switch off the current measurement and

to apply the standby voltage U.standby to the electrodes. The dropping

mercury electrode DME is also switched off, i.e. the mercury flow is

stopped.

Comment If the solution in the measuring vessel is changed during the program

run (e.g. in the recording of calibration curves), the ØMEAS instruction with

no standby voltage set (U.standby = empty) must be inserted before the

solution change so that no voltage flows through the electrodes.
