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

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 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. 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).
