Sending Email messages
11.4 Sending Email messages
The instrument is equipped with the email transmission function. You can send email messages to
computers in the network or to those installed in remote locations via the SMTP server. Moreover,
you can install the instrument in a remote location and collect measured data through an email
attachment.
How to send email messages
Auto-save email message Automatically sends an email message with data saved on completion
of measurement attached, according to the auto-save settings.
Set [Auto save settings] to [On] and choose [Mail] in the [Media] box
in advance. (p. 84)
Manual email transmission with
the save icon
When you click the save icon, an email with the data saved attached is
automatically sent. Set the [Media] box of the manual save setting to
[Mail] in advance.
Test email message Checks if an email message is successfully sent.
Encryption of email attachments
You can encrypt email attachments, such as screen data and measured data, to prevent it from
getting into outsiders.
• If transmission conditions are frequently satisfied, email messages will frequently be sent.
• Data size of an email attachment may get extremely large. Depending on the communication
environment, an email message cannot correctly be sent if the size is extremely large.
• Email attachment data is encrypted in ZIP format by WinZip 128-bit AE-2 / AES encryption.
Encrypted files can be unzipped by Corel WinZip or free software such as 7z. (The WinZip AES
encryption is much securer than the standard zip encryption; however, supporting software
is limited. The built-in ZIP feature of Microsoft
®
Windows
®
cannot unzip encrypted files in this
format.)
• Files are encrypted by 128-bit AES encryption. Presently, this encryption method is sufficiently
strong; however, Hioki does not guarantee that files are never decrypted.
• Do not reveal your encryption password to outsiders. Note that you cannot decrypt any files if you
forget your password or enter an invalid password.
• When you have set or changed the password, send a test email message first to check whether
you can unzip an attachment before actual use.
• Encrypted ZIP files are not compressed.
• When files are encrypted and zipped, sending email messages require a long time due to
conversion time.
• The instrument supports pop-before-smtp and smtp-auth (PLAIN, LOGIN, CRAM-MD5) as the
SMTP authentication (since the instrument does not support IMAP, SSL, or STARTTLS, you
cannot send email messages to some mail servers, such as Gmail).
• We cannot guarantee transmission to all SMTP servers due to differences among servers.
• AES is the encryption standard specified in the U.S. Federal Information Processing Standard
(FIPS) PUB 197.
• The instrument have no email reception function but the transmission function.
• You cannot load any compressed and encrypted data as it is on the instrument or on the Wave
Viewer (Wv).
