1.4 Overview

The OM-DAQXL is an 8 or 16 analog input portable data logger with a color
7" resistive touch screen display. It has user programmable inputs that can be
configured for several different types of sensors including temperature sensors
(thermocouple, RTD, thermistor), strain gage, process inputs (voltage and
current) and digital pulse inputs. All configurable options (including individual
channel input type and range) are software programmable. The device is
powered by a 7.2V, 4.8 Ah Li-ion battery. In addition an external 12V, 5A AC
adapter can be used to power the device for extended periods.
The compact, portable packaging ensures ease of use in a variety of applications.
Devices can be wall mounted using the provided keyhole mount or easily

The OM-DAQXL has been designed to meet its stated specifications when
operating within the ambient conditions outlined below.
Temperature: 0 to 50 deg C (32 to 122 deg F)
Humidity: 0 to 95% RH non-condensing
In addition to restricting operation of the data logger to the given temperature
and humidity ranges, a warmup period of 30 minutes is recommended to ensure
best accuracy of measurements.
