Product Overview
The OM-CP-VOLT101A data loggers are versatile data logging devices with many uses and applications.
Connect negative and positive wire leads directly to the terminal port on the OM-CP-VOLT101A to
monitor and measure voltage levels. The OM-CP-VOLT101A is commonly used to assess battery efficiencies
or photovoltaic studies to identify how much energy is being created from solar cells.
The OM-CP-VOLT101A features a removable terminal block to allow for simple retrieval of the data logger for
downloading while leaving the leads connected. With a ten year battery life and the ability to store up to one
million time and date stamped readings, this device is ideal for long term deployment and voltage studies.
Four models of the OM-CP-VOLT101A are available. The 2.5V is capable of measuring -3V to 3 V, the 15 V
capable of measuring -8V to 24V, and the 30V which can measure from -8V to 32V. For lower voltage
applications that require a higher resolution, Omega also offers the OM-CP-VOLT101A-160MV model,
which can measure voltage between -160 and 160mV.
Wiring the Data Logger
OM-CP-VOLT101A, 2.5V, 15V and 30V models
Single Ended Wiring
OM-CP-VOLT101A-160MVDC
Differential Wiring
Two-position removable screw terminal connections; accepts
2-wire configurations.
Three position removable screw terminal connections,
accepts 3 wire configurations.
Warning: Note the polarity instructions. Do not attach wires to the wrong terminals.
LEDs
- Green LED blinks: 10 seconds to indicate logging and 15 seconds to indicate delay start mode
- Red LED blinks: 10 seconds to indicate low battery and/or memory and 1 second to indicate an alarm condition
Engineering Units
Native measurement units can be scaled to display measurement units of another type. This is useful when
monitoring voltage outputs from different types of sensors such as temperature, CO2, flow rate and more.
Password Protection
An optional password may be programmed into the device to restrict access to configuration options. Data may
be read out without the password.
Multiple Start/Stop Mode Activation
- To start device: Press and hold the pushbutton for 5 seconds, the green LED will flash during this time. The
device has started logging.
- To stop the device: Press and hold the pushbutton for 5 seconds, the red LED will flash during this time. The
device has stopped logging.
Alarm
User selectable high and low voltage limits.
