vPad-RW OPERATING MANUAL
1Throughout this manual, IEC 60601-2-21 is referred to as the “Standard”
Overview/Chapter 2 # Page 5
2 General Information
2.1 Overview
vPad-RW is a portable datalogging system for temperature, air flow, and sound level;
specifically configured to test infant radiant warmers and, optionally, incubators and transport
incubators to applicable IEC performance standards. The data collection system is designed to
operate for up to 48 hours from a rechargeable 4.8VDC nickel-metal hydride (4 AA cells)
battery, or alternatively, from a 5VDC switchmode AC adapter. The sensors and the data
collection system are placed on the mattress of the radiant warmer, and external to the device
under test (DUT), a user interface based on an Android tablet communicates wirelessly to the
sensor system via Bluetooth, and provides the user with the ability to control the test operation
and display the results without disturbing the test environment.
vPad-RW incorporates all the functionality necessary to meet the requirements of the IEC
standards, related to temperature, airflow and sound level tests. vPad-RW incorporates a
graphical user interface which interfaces wirelessly to 5 temperature sensors, 1 airflow sensor,
and 1 sound level meter. vPad-RW also incorporates a non-volatile memory or "data log" which
is used to save test data, such tests typically being conducted by the user over several hours or
days.
2.2 Features
IEC 60601-2-21
1
is a standard which specifies safety and performance requirements for an
infant radiant warmer. Some of the parameters that lend themselves to testing are temperature,
sound level, and air flow. These parameters are monitored at specific locations within the
radiant warmer and are expected to conform to the values defined by the Standard. vPad-RW
provides a mechanical framework to hold the sensors in the appropriate locations, and provides
the ability to adjust the framework to fit warmers of various sizes.
vPad-RW provides 5 temperature sensors which are positioned according to the Standard, with
one central sensor and one sensor in the center of each of four quadrants on the mattress. The
central sensor is an integral component of the data collection and wireless communication hub

vPad-RW OPERATING MANUAL
Overview/Chapter 2 # Page 6
of the system. In addition to the 5 temperature sensors, vPad-RW provides airflow, and sound
level sensors in separate packages which connect to the central hub. The test protocols are
designed to perform all the temperature tests in one contiguous time block to avoid numerous
long heating and cooling cycles. Tests of airflow, or sound are performed either before or after
the temperature tests so that the sensors can be moved about in the radiant warmer without
disrupting a temperature test.
2. Controls and Interface Connections
Referring to Figure 1 through Figure 6, the following components, controls and interfaces of
the vPad-RW Radiant Warmer Test system are:
Note: the hardware components for vPad-RW are virtually identical to vPad-IN. The
differences are in the setup, and which temperatures to measure. If the user has one of the
systems (hardware), only the software is needed to do the other EQUIPMENT (incubator).
1. Sensor Electronics and Wireless
Hub (the HUB)
Provides the connection point for all sensors used
internally to the incubator or warmer under test.
Also referred to as the DAT unit
2. Temperature Connectors Temperature Probes (T1 - T5) are connected on
the top of the large, black thermal mass (Puck) to
place the thermistor in the correct position above
the mattress. T6 - T10, Temperature Probes are
embedded in the thermal mass (Puck) for use in
radiant warmers.
3. Thermal Mass (the Puck)Thermal mass to mimic the infant body for
convection warming in a radiant warmer. Contains
Magnetic Fasteners (3.b) for attachment of other
sensors
4. Temperature Probe (T1 - T5) Bypasses the thermistor in the Puck and places the
thermistor at the correct position above the
mattress, per the Standard. For use with vPad-IN
5. Mattress Temperature Measures the temperature of the mattress. For use
with vPad-IN
6. Airflow Probe Measures the flow of air, and can be moved as
required. Held in place on the Puck magnetically.
