4. Design and function / 5. Transport, packaging and storage

4.4 Battery selection

The CEP1000 is operated with a normal 9 V alkaline battery or optionally with a
rechargeable 9 V Ni-Cd battery. For the most application cases the alkaline battery with
9 V is sucient. However, for the intensive use the 9 V Ni-Cd battery is the better choice.
The Ni-Cd battery for 9 V available optionally with an output current of 12 mA and full

battery enables continuous operation for approx. 3 hours (the alkaline battery lasts

approximately 12 hours). The optionally available charging device charges the battery
over night (10 to 12 hours long) and powers the instrument in the stationary mode. At

the same time the conservation charging of the Ni-Cd battery is carried out.

WARNING!

Never connect the power supply unit/charging device if a 9 V alkaline

cell is inserted.

4.5 Input protection

The device has an input protection without a fuse for up to 250 V of direct or alternating
current for the period of time of up to 30 seconds.

the output signal.

For further information refer to the section "6.3.1 Automatic operation modes" of the

instruction.

6.2.2 Milliampere simulation

Figure 4 shows the way the CEP1000 is connected if it is supposed to function as a
2-wire transmitter with an external power supply. In this case the circuit is powered via
an external voltage source and the instrument just regulates the current in the circuit.
The regulating procedure of the output signal is the same as for the application as the
source of current in the milliampere range.

6.3 Advanced operating modes

6.3.1 Automatic step function/automatic ramp mode

The CEP1000 is capable of increasing the output current in the mA range in steps of
25 % automatically with intervals of 5 seconds. The output current in the mA range
can be increased linearly in form of the ramp function from 4 mA up to 20 mA and then
reduced again automatically to 4 mA.
To activate the automatic step/ramp function proceed as follows:

1) The automatic step/ramp function can be used for the application as milliampere

source as well as for the milliampere simulation. Switch the instrument into the corre­sponding operating mode.

2) Connect the CEP1000 to the instrument to be tested.

3) For the automatic step function press the "AUTO" key once, for a slow ramp function

twice and for the quick ramp function three times. After every key stroke a small

conrmation window appears in the lower left corner of the LCD display, it indicates

which step function or ramp function has been selected.

4) As soon as the step function/ramp function has been activated, it is functioning

constantly until another key is pressed.

6.3.2 Fault percentage function

This unique function calculates the fault percentage of the measuring range (a measur-

ing range of 4 ... 20 mA gives a span of 16 mA). Using the function for calculation of fault

percentage the user can "Zero Out" the milliampere indication, thus, enabling indication
of deviation from the ideal value on the display as a fault percentage.

Procedure:

1) Connect the CEP1000 to the instrument to be tested.

2) Set a mode with milliampere output for the instrument (source or simulation).

3) Set the required output value.

4) If the instrument to be tested does not measure the exact value, press and hold

the "%ERROR" key and adjust the knob so that the instrument displays the correct
value. Press and keep holding the “%ERROR” key further on.

5) The indication in the percentage eld corresponds to the fault or deviation as a

percentage of the span.

6) After the "%ERROR" key has been released, the indication switches back to normal
operation.

6.3.3 Data acquisition for minimum and maximum

If the CEP1000 is operated in a measuring mode (milliampere, milliampere with power

supply or voltage), the minimum and maximum values for the corresponding input mode

GB

are monitored and stored permanently. To activate the data acquisition proceed as
follows:

1) Switch the CEP1000 to a measuring mode.

2) Connect the instrument to the instrument to be tested.

3) Press both keys (“MIN” and “MAX”) to clear the memory for the minimum and

maximum values. The “CLR” message is displayed on the LCD display, if the
memory has been deleted.

4) Acquire the minimum value and the maximum value using the instrument as long as

required.

If necessary, deactivate the battery saving function prior to calling the
data acquisition function to avoid premature switching o of the calibra­tor.

5) The saved value can be accessed any time by pressing the "MIN" or "MAX" key.
