11.2 Analogue output
An analogue voltage of 0-1 V can be tapped at the universal output jack (Out dAC setting).
With DAC.0 and DAC.1 the analogue output can be scaled very easily.
It must be ensured that the analogue output is not too heavily stressed, otherwise the output
value can be falsified and the power consumption of the device increases sharply. Loads of
up to approx. 10kOhm are harmless.
If the display exceeds the value adjusted with DAC.1, 1V is output.
If the display undercuts the value adjusted with DAC.1, 0V is output.
In the event of an error (Err.1, Err.1, etc.), a voltage slightly above 1V is output at the ana-
logue output.

12. Adjusting the temperature input

With offset and scale the measurement inputs can be adjusted, both the voltage measurement
and the temperature measurement. Requirement: Reliable references are available (e.g. ice
water, regulated precision water baths, etc.):
If an adjustment is made (deviation from factory setting), this is signaled with the message
"Corr" when the device is switched on.
Standard setting of the zero point and pitch values is: "off" = 0.0, which means no correction
is made.
Only offset correction:
Displayed value = measured value - setpoint
Offset and pitch correction:
Display = (measured value – OFFS)
Display = (measured value °F - 32°F - OFFS)

13. GLP

The regular monitoring of the device and accessories is a part of the GLP (Good Laboratory
Practice).
Prerequisite for the use of the GLP functions is that the electrode is not replaced. The data is
saved in the device, however, it is based on the respective electrode.

13.1 Calibration interval (C.Int)

You can specify a fixed interval at which you automatically remind the device that a new
calibration should be performed and/or the calibration is no longer valid.
In the process, the length of the interval depends on your use and the stability of the electrode.
As soon as the interval has lapsed, "CAL" blinks in the display.
