4. USE
Once your instrument has been congured, you can use it. You must still:
 Congure the measurement channels,
 Connect the probes, sensors, transmitters, or signal conditioners
 Start a recording session
4.1. CHANGING A PARAMETER
To change a parameter, press

; this changes the rst eld on the screen that can be modied to reverse video. Use the 
 keys to select the eld you want to modify, then press

again to edit the eld. Then use the  or  key to dene the eld. If
the eld comprises several characters, use the  or  key to go from one character to another.
When you have nished, press

to validate.
The numbers are not changed digit by digit, but more globally.
For example, to go from 0.00 to 85.00, start on the left-hand digit, before the zero, and press . The digit will be incremented
repeatedly. When it reaches 8, shift the cursor to the second digit and change it in the same way. And so on.
For a negative number, start on the left-hand digit, before the zero, and press . The digit changes to 00.00, then to -10.00, then
-20.00, etc.
4.2. CONFIGURING THE MEASUREMENT CHANNELS
From the Measurement data screen (see Figure 7), press  twice.
 From this screen, you can activate or deactivate measurement
channel 1 and choose the type of input:
 pulse
 event (discrete)
 4-20mA current
 ±10V, ±1V, or ±100mV voltage
CHANNEL 1:
ENABLED
INPUT:
±100 mV
It is not possible to deactivate both channels. If you deactivate channel 2 when channel 1 is already deactivated, channel
1 is automatically reactivated. This makes it impossible to start a recording session with both channels deactivated by
mistake.
UNITS:
CHANNEL 1:
 Press  to go to the next screen and enter the unit of channel
1 in 4 characters.
If you do not specify a unit, the default values will be:
 mV for ±100 mV
 V for ±10V and ±1 V
 mA for 4-20 mA
 Wh for pulse
For an event input, you can choose whether triggering is on
the positive-going or negative-going front.
TRIGGER:
