Current Measurement
CEP1500 supports current measurement using either CEP1500 as the loop power supply
while at the same time measuring the current or simply measuring the current while an
external power supply is used.
The following picture displays the connection for Current Measurement for different mode.
And also different ways of providing the supply power to the loop.
mA Current Measurement
In this mode CEP1500 not providing any supply voltage. For proper measurement the
external device should capable of providing the voltage supply. If the external device should
not capable, an external Power Supply should be connected in series.
mA Read Power Current Measurement
In this mode CEP1500 works as Loop Power Supply while at the same time measuring
the current.

 Procedure to Open Stand
o is being engraved on the top of the stand. You
should pull a bit first.
o is being engraved on the bottom of the stand. Now
during first pull of above you can release this lower
part easily so that you can maneuver the stand as you like.
There are three power options:
 Lithium-Ion battery: All the instrument functions are available with a charged battery.
 5 V DC Charging Adaptor: It supplies power to the instrument and charges the battery
at the same time. It charges the battery when the instrument is on or off.
 USB mini Type B connection: This charges the battery when the instrument is off and
increases the battery life when the instrument is on.
The Device uses 2300mAh Lithium-Ion Battery.
 To prevent an explosion or fire, do not short circuit, do not disassemble, and keep
it safe from damage. For operating conditions, see section 6.1 on Page-Error!
Bookmark not defined..
 To prevent an explosion or fire, use only the WIKA specified battery, battery
charger & USB Cable.
 To prevent battery leakage or heat generation, only use the battery charger in the
temperature range 0 to 45°C (32 to 113°F). For operating conditions, see section 6.1
When you set the power on, the battery symbol at the top of the display shows the charge
Status. To get more information on Battery go to Battery Info Page in Setting Menu.

Note: USB mini Type B connector charges the battery when the instrument is off and
increases the battery life when the instrument is on.
These are typical operating times for a new, fully charged Li-Ion battery pack with these
settings:
 Backlight Intensity set to 5% (Default: 100%)
 Backlight Timeout set to 0 (0=Infinite) (Default: 0)
Power save options: To get the best battery duration, set a low value for the Backlight
Intensity (40%) and a short Timeout.
The maximum operating time without recharging varies depending on the usage and
brightness setting of the display light. Also the generated output current and the usage of the
24V transmitter supply affect the maximum operating time.
Notes:
 CEP1500’s memory and the internal clock/calendar use a small amount of power although the
calibrator is switched off. Remember to check the capacity of the batteries from time to time
although CEP1500 is not in use.
 Do not leave CEP1500 without a Battery Pack or an Empty Battery for a long time. CEP1500
may lose its settings if it is left without a support voltage for an extended-period.
