3.0 Safety information
3.1 Safety compliance
The equipment meets the requirements of international safety standard IEC 61010-2-030:
Safety requirements for electrical equipment for measurement, control, and laboratory use:
Particular requirements for equipment having testing or measurement circuits.
3.2 Safety symbols
The symbols below are marked on the equipment and throughout this manual to indicate:
Read these instructions before installation or use of the datalogger
Warning, hazard: read these instructions before proceeding to ensure you
understand the nature of the hazard.

sq 16 Datalogger
Operating Manual Page 6
www.grantinstruments.com
3.3 Safety warnings
Use only as specified by the operating instructions: if the equipment is used in a
manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
Do not connect the logger to hazardous voltages:- because it is floating with
respect to earth, the hazardous voltage can appear on other terminals (as well
as damaging the logger).
The insulation of the wiring used to connect to the sensor inputs must be
adequate for the voltages to be measured. This means for example that at least
75V rated insulation is required if using the -25V to +50V range (sq16) and that
at least 100V rated insulation is required if using the -40V to +60V range
(sq16plus).
The logger is designed to be powered by a class II power supply (no Earth
connection) for maximum flexibility.
Remove the batteries when the logger is not used for long periods of time or is
being transported
This logger is not designed for safety critical applications: do not rely on it to
verify safe conditions before carrying out any potentially hazardous activities.

4.2 Powering sq16 data loggers
Fit the AA Manganese alkaline batteries when remote or mobile operation is required and to
ensure logged data protection in the event of unexpected mains power loss. The battery
compartment is at the rear of the logger, observe battery polarity.
When batteries are first fitted, and they are the only power source, then press and hold the
Control & Status button until the lights up and then release to power up the logger.
It is recommended that replacement batteries are of the same manufacturer, type, and
condition.
Power can be provided by a USB connection from a powered USB socket in a PC or Laptop.
For continuous use where mains power is available, plug the MPU 12V mains adapter into
an accessible mains outlet. Insert the Jack plug into the sq16 External power input.
Only use the mains adapter supplied by Grant Instruments for the external power source
Always power your sq16 logger using the mains adapter if external sensors powered by the
logger are being used.
The logger is designed to be powered by a class II power supply (no Earth
connection) for maximum flexibility.
Remove the batteries when the logger is not used for long periods of time or is
being transported

4.6.1 SquirrelView Homepage
The SquirrelView Desktop homepage is the main interface for connecting and managing
Squirrel data loggers and data.
The top of the homepage has details regarding the software version, the possibility to reload
and refresh the software and gain access to the hub settings if connected.
Below this is the main ribbon which is arranged in 4 main sections. These handle set up,
actions during logging, handling job files and data sets as well as the option to check logger
alarm status.
Below the main ribbon and to the left side are three areas which can be expanded or
collapsed by clicking on them; the Device Tree, Datasets and Setup Files.
Under the device tree is the connection icon . When connecting a logger with a USB
cable, click this icon to make a connection and use the software.

4.6.3 Channel Setup
On the right side of the display, click on the Channel Configuration tab to add or edit
channels
Note, the above schematic refers to the input pins in each of the four blocks of the logger:
There are 5 different types of channels that may be measured and recorded by the sq16,
and sq16plus loggers, these are:
Analog –for Resistance, Voltage, Current, Temperature (Thermistor, Thermocouple, PTD)
Calculated –Log mathematical calculations on measured channels
Pulse –Pulse count and pulse rate measurements
Event –Monitor and record the digital inputs as a number (0-255) or state (8 bit)
Reference Junction –Log the internal thermocouple reference junction temperature
Sensor inputs, pins 1 to
5 in blocks A,B,C and D

sq 16 Datalogger
Operating Manual Page 18
www.grantinstruments.com
To add an Analog channel, click on the channel configuration icon and select the appropriate
sensor/probe type from the drop down menu:
Select location in the example, Block A, Channel 1 is the default, click Add Channel.
The software will show the probe input positions corresponding to the logger input pins:
Repeat for other probes. Hint, use the copy function if the probes are the same type:

sq 16 Datalogger
Operating Manual Page 19
www.grantinstruments.com
In the example below, 12 type T thermocouples are configured in single ended mode.
Note, the software will always offer the next available channel for the selected probe type by
default.
4.6.4 Editing Sample and Logging intervals
The Default logging method is Interval and default Sample and Logging Intervals are 1 per
second. These may be changed by clicking on the which opens the Logging Method
menu:
Clicking on the opens the Logging Method menu.
Logging Method
This specifies how the readings taken for a channel are logged to memory, there are
following different logging options:
Interval
Readings are stored at every Logging Interval. This is the default setting.

sq 16 Datalogger
Operating Manual Page 20
www.grantinstruments.com
Average
Readings are taken at every Sample Interval and the average of these are stored at
every Logging Interval.
Minimum & Maximum
Readings are taken at every sample interval and the maximum or minimum of these
are stored at every Logging Interval.
Sum
Readings are taken at every sample interval and the sum is stored at every Logging
Interval.
Sample Only
Readings are not logged
Note on Sample Interval, Sample Count and Logging Interval
The sample interval default is 1 second, this means all channels are monitored every
second. Readings are not necessarily logged and stored every second, as the Logging
Interval determines this. To increase the time between logged readings, edit the Sample
Count whilst leaving the Sample Interval at 1 per second. For example, in the following with
a Sample Interval at 1 second and a sample count set at 60 the logger will save readings to
memory every 60 seconds:
