6 CALIBRATOR - FUNCTION SELECTION
The calibrator functions are selectable with three sliding switches. The keyboard permits setting of
Ramps, Steps or direct Value entry.
The Multimeter is active all the time and can be simultaneously used with the calibrator. The function is
described in § 7.
The display is divided into two parts. The upper part shows the multimeter values, the lower part is
assigned to the calibrator outputs 0-20mA or 0-10V. The middle part is a Bargraph showing the values
as analogue information.
6.1
Setting of the output current 0 - 22mA in Steps or Ramps
Sliding switch to be set to SRC-I and OUT-I.
The key Clr set the output current to 4mA.
The key Up increases the output current in 0.20 mA steps.
The key Down decreases the output current in 0.20 mA steps.
The key Ramp activates the automatic ramp. To stop the ramp, press the key again.
The key Step generates the current steps of 4, 8, 12, 16, 20, 22mA
6.2
Direct setting of the output current between 0 and 22mA
Sliding switch to be set to SRC-I and OUT-I.
The key Num activates the numeric selection.
Enter the required value with the keyboard and press Enter.
To erase the last entry, use the keys

6.3
Setting of the voltage output 0 - 14 V in Steps or Ramps
Sliding switch to be set to OUT-V.
The key Clr sets the output voltage to 0 V.
The key Up increases the output voltage in 0.10 V steps.
The key Down decreases the output voltage in 0.10 V steps.
The key Ramp activates the automatic voltage ramp.
The key Step generates voltage increments 0, 2, 4, 6, 8, 10, 12, 14V.
6.4
Setting of mV Outputs 0–560mV and 0–28mV in Steps or Ramps
Same like 0–14V voltage output. Menu selection: Select 2 or Select 3.
6.5
Thermocouple output in Steps or Ramps
Put the Sliding Switch into Position OUT-V.
Press MENU until the display shows VOLTAGE OUTPUT U.
Select 4 with MENU.
THERMOCOUPLE OUTPUT. Select the required Type.
Select Cold Junct. Comp. Select 1 (ON) for internal on-board compensation. Press MENU.
Select Unit Selection. Select 1 for degree Centigrade (ºC). Press ESC.
Key Clr sets the output signal to 0.0 ºC.
Key Up increases the Output mV in 10 ºC steps.
Key Down decays the Output mV in 10 ºC steps.
Key Ramp activates the automatic Ramp generation.
Key Step generates Output mV in Steps 0, 200, 400, 600, 800, 1000, 1200, 1400 ºC
RAMPS
The key Ramp activates the Ramp Generator. The display increments or decrement in steps selected
in the Menu and shows the symbol RMP. With the key Ramp the Ramp can be stopped. When
pressed again, the Ramp will continue from the value when it had been stopped. By keeping pressed
the key Ramp for several seconds, the Ramp will start from beginning.
