6 PRACTICAL USE AND PROTECTION
This thermometer is a highly sensitive measuring device.
Therefore prevent shock from the thermometer body or
sensor.
Do not drop the thermometer housing.
Do not drop the thermometer sensor / probe.
The thermometer housing is of thermoplastic and sensitive to
heat. Prevent operating the thermometer at temperatures
higher than ambient.
The temperature sensor is of stainless steel. Prevent
temperatures higher than 250°C at the tip of the sensor.
Keep the thermometer away from water and dust.
Keep the serial connector and sensor connector (PT100)
away from water. Corrosion of the PT100 connector will
seriously influence the calibration.

7 SPECIFICATIONS
7.1 Use conforming to ASTM E2877
The E20 Thermometer specifically is designed to be used
conforming the standard guide for digital contact
thermoemters ASTM E2877. This Guide describes general-
purpose, digital contact thermometers or “digital
thermometers” that provide temperature readings in units of
degrees Celsius or degrees Fahrenheit, or both.
The thermometer conforms to the highest accuracy class type
“A” of the described 9 classes “A” to “I”
7.2 Accuracy
For technical specifications see Dimensions and performance
page 20.
7.3 Response time
For technical specifications see Dimensions and
performance page 20.
The fast response to temperature changes of the E20
thermometer ensures a T63 response time of less than 3
seconds. That means that at least 63 percent of the
temperature change is displayed within three seconds. The
E20 thermometer is equipped with a 3 mm outer diameter
shaft. Differences in response time are indicated in figure 1.

The response time is a very important parameter. When using
a thick metal PT100 probe, it appears as though the
temperature reading is stable (indicated by the light green line,
figure 2). However this false stability is caused by the large
thermal mass of the probe. This thermal mass prevents rapid
temperature changes so it looks like the temperature reading
is stable. This phenomenon gives a technician a false sense
of temperature stability. It's not a stable temperature but the
PT100s' thermal mass masters the temperature fluctuations
which results a feeling of having a stable temperature. In
reality the dampened temperature fluctuations may result in
significant error during viscosity measurement. Depending on
the pt100 probe-mass misreading's in the range of 0.1°C are
easily possible.
Another disadvantage of a long response time is that it takes
longer for the thermometer to reach the true temperature. This
difference is indicated in figure 3 below

1 Connector power / communication
2 OLED display
3 Button
4 PT100 shaft diameter 6mm
5 PT100 tip
8.1 Start
Connect the power cord to the connector on top of the
thermometer.
Connect the USB connector of the power cable to the USB
power adapter
The thermometer will light up.
8.2 Menu structure
When switched on, select the temperature readout:
Degree C, "°C"
Degree F, "°F"
Digital, "B"
8.3 Communication
The communication between PC and E20 thermometer uses
a protocol based on addresses. In the microcontroller data is
stored in EEProm using memory addresses. The
temperature is stored at memory address 376, 377, 378 en
379. Four bytes are stored at this address to form a float.
The protocol between the PC and thermometer is a copy
function as it copies a variable of bytes from or to the
computer.
The temperature is a 32 bit signed float thus four bytes of
data are exchanged
Running at 19200 baud, 8 data bits, no parity
The data from and to the PC is exchanged using a so called
package:

8.4 Protocol
'Byte 1 Synchronisation, decimal 84 (this is a fixed
character)
'Byte 2 Length of package, 7..255.
Each package needs a minimum of 6 bytes
These 6 bytes are the so called overhead:
Byte1,2,3,4,5,7
A package is formed by these six bytes plus
additional data.
'Byte 3 Command
bit 0
0 = data read
1 = data write
bit 1 and 2
00 = not used
01 = Location is SRAM
10 = Location is FLASH
11 = Location is external EEPROM
'bit 3
0 = No extra routine
1 = Set Real Time Clock
'Byte 4 Address high byte
'Byte 5 Address low byte
'Byte 6 Data, the actual information - 1 to 248 bytes
'Byte 7 Checksum, all data is added, last two hex are used.
I.e. a value of &h 30D returns 0D as checksum.
8.5 Send and receive
In order to receive the actual temperature from the E20
thermometer following hex code must be send to the
thermometer:
54 0A 02 01 77 00 00 00 00 D8
(The red value "D9" is the checksum)
Now assume the thermometer reads 25.147°C, than the
response from the thermometer will be:
54 0A 02 01 77 63 2D C9 41 72
In Red the checksum
In Green the temperature indicated in hexadecimal
Please note that the LSB is send first whilst the MSB is last.
So the data must be swapped:
41 C9 2D 63

This 32bit HEX data must be converted to a float. The value
of &H 41 C9 2D 63 is 25.1472.
One can use a HEX to Float converter like
https://gregstoll.com/~gregstoll/floattohex/
Or look at Wikipedia on how to converte a 32 bit Hex value
into a floating point.
