After investigsting further I'm convinced the low batt message must be a funny 'quirk' of this tester when a poor contact exists during continuity test. It happens with all lead combinations when a poor contact exists but it is mostly noticeable when using the spring loaded part of the probes (eg plugging probes directly into null adapter as instructed) since this part introduces a poor contact.

Would be handy if someone else with a 1664 could confirm.

Thanks for help

I think it would be worth getting in touch with Fluke or the seller as this doesn't sound like something a top of the range tester should do.

For what it's worth, I have the 1654 and don't have any problems using any of the leads or probes with the null adaptor - readings are always consistent and no error or low battery messages.

Basic issue:
New Energizer alkaline batteries in meter....


.... but I can't understand why I am receiving Low Batt message in continuity mode when simply shorting probes into null adapter & wiggling them, has anyone else seen this?


Thanks for any advice

a) Do batteries get flat extra quickly ?
( Has meter suffered a bad fall - got worst from then on == Cracked capacitor -draining extra power == Or more expensive part )

b)--Do also check battery compartment for any residue -causing an occasional poor contact
--So it receives poor power -- Indictated battery voltage moves about if tap meter gently
--(I suspect) Low ohms continuity ,draws the most current from the batteries - Possibly showing signs of a weak "single-bat" / dirt / or fault.

just as a hijack, a lot has been said about how accurate MFT's are on no-trip Zs. doing a EICR yesterday and just out of interest i tried my Megger 1553, 11 years old, on both. (at the same socket outlet). hi current 0.25. no-trip 0.26. good enough for me. probably the 0.01 is due to the hi current test warming the cables and thus making a slight increase in resistance... o_Oo_Oo_Oo_Oo_O:laughing:.
 
I've reasoned the low battery message maybe a design fault since everything else works fine.

Checked the unit is genuine which it is & still has 2 years warranty.

I figured it maybe something to do with the high current continuity test, my thinking being:
High current continuity test underway - Meter is providing a regulated high current to carry out the test. Probes disconnected quickly (scenario which occasionally shows fault) so circuit suddenly becomes open circuit, meter attempts to regulate it's high current by increasing test voltage which would suddenly draw additional current from the battery to do so. This surge may cause the battery voltage to dip or perhaps the internal psu can't support it causing a low batt warning message?
 
Do throw some decent ,Duracells in it before condemning it due to a
batch of stale batteries !
(re reading manual --ERROR-5)
Is all about noise ,poor contact.
So maybe you are confusing it!
Make a good connection
-before TEST !
