@jccantrell Didn't say I had an issue with your suggestion - in fact, I don't. My "at all times" option was merely one for added emphasis; same with "always."

E.g.,
"A basic rule of driving is that, at all times, the driver of a vehicle on a highway shall control the vehicle as necessary to avoid a crash."

PS:
Here's "keep" + "at all times" from ENS pages:

@Björn and phil I thought about adding another word or phrase, but I think 'keep' is sufficient in English. After all, if you do not tune it constantly (if it wanders or drifts), then you are not keeping it tuned, nicht wahr?

Björn Vrooman May 26, 2017:

@jccantrell What do you think about adding "at all times"?

Otherwise, agree with Phil: Post it - although there must be a way around repeating "channel 1" - "relevant" / "this" / "above-mentioned" (don't have the context)?

@Phil
"I don't think your dictionary is correct."

Not surprising. Most of these seem to have been compiled by one or two people (most likely Germans).

Although in the author's defense, he or she is not wrong, just could have given both options, I guess:
"Since the mid-19th century, many grammarians have drawn a distinction between continual and continuous. Continual should only mean 'occurring at regular intervals,' they insist, whereas continuous should be used to mean 'continuing without interruption.' This distinction overlooks the fact that continual is the older word and was used with both meanings for centuries before continuous appeared on the scene. The prescribed sense of continuous became established only in the 19th century, and it never succeeded in completely driving out the equivalent sense of continual."

It's an artificial distinction.

jccantrell Why not put your second suggestion as an answer?

jccantrell May 26, 2017:

How about 'constantly?'

Or maybe just 'Keep channel 1 tuned to the channel 1 sensor voltage.'

I don't think your dictionary is correct. Surely it means continuously, not continually.
