2. Use the arrow keys to set the minutes and confirm with
[OK]
.
The display flashes briefly.
The timer is programmed and active.
The decimal point flashes on the display until the setpoint temperature is
reached. The timer starts once the setpoint temperature has been reached. In
the last 30 seconds, the actual temperature and the remaining operating time
are displayed alternately.
After the set time has elapsed, a double acoustic signal sounds and the device
switches to standby mode.
The setpoint temperature can still be changed until it is reached. The timer
remains active and starts when the new setpoint temperature is reached. If the
setpoint temperature is changed while the timer is running, the timer is
deactivated.
Press the
[OK]
key to stop the running timer.
8.7 Adjusting the temperature sensor (ATC)
For physical reasons, there can be a temperature difference in the bath tank
between the temperature sensor and a defined, more remote point within the
bath fluid volume. As a result, the measured temperature deviates slightly from
the actual bath temperature. Adjustment of the temperature sensor can increase
accuracy of the temperature control application.
The bath tank is filled.
The unit is switched on.
1. Hang the calibrated thermometer in the bath tank and place the bath lid on
top.
2. Set the desired setpoint temperature and start the temperature control
application.
When the setpoint is reached, allow the temperature to stabilize for several
minutes.
The more stable the temperature in the bath tank, the more precise the
adjustment result.
3. Simultaneously press the Service key and
[Down Arrow]
keys until the
decimal point flashes.
4. Enter the read reference temperature and confirm with
[OK]
.
The calibration value is applied directly. The display shows
<CAL>
for
confirmation.
The entered reference temperature must be within ±5°C of the setpoint
temperature, otherwise an error message appears and the entry is ignored.
The temperature sensor is adjusted.
