2 Basic Operation
2.1 Measure and Source
This section acquaints you with some basic operations of ETX-2015/ ETX-1815.
Proceed as follows:
1. The connection of the calibrator as shown in Figure 2.1-1.
Figure 2.1-1
6
2. Press more than 2 seconds to turn on the calibrator. The calibrator checks
itself, including check on internal circuit and LCD, during which, LCD displays
all contents for 1s as shown in Figure 2.1-2:
Figure 2.1-2
3. Then the product model（2015）and automatic shutdown time（30 min）will
be displayed for 2 seconds as shown in Figure 2.1-3.
Figure 2.1-3
4. Press switch to the voltage mode.
5. Press to enter into output mode selection as shown in Figure 2.1-4.
Figure 2.1-4
6. Press and to increase or decrease 1 of the horizontal line position (the
number automatic carry but the position of the line have no change); press or
to select a digit to change.
7
7. Press to select 1 V for the output value, and then press and hold
until the buzzer works to enter 1V as the 0% value.
8. Press to select 5 V for the output value, and then press and hold
until the buzzer work to enter 5V as the 100% value.
9. Press or to step between 0 and 100% in 25% step increments.
The screen will display as shown in Figure 2.1-5.
Figure 2.1-5
2.2 Shut Down Mode
The calibrator comes with the shutdown mode enabled for a time duration set to 30
minutes (displayed for about 2 seconds when the calibrator isinitially turned on). When
the shutdown mode is enabled, the calibrator will automatically shutdown after the
time duration has elapsed from the time the last key was pressed. To disable the
shutdown mode, press and simultaneously. To enable the mode, press
and simultaneously. To adjust the time duration, press and
simultaneously, the screen will display as shown in Figure 2.2-1,then press and/or
to adjust the time between 1 and 30 minutes and then press to store the
new time duration (Without pressing any key for 5 seconds, the calibrator will quit
from the adjustment automatically).
