Who's got some Ideas on how....

[Tech it out]

The new clamps I bought last week have much improved wire.

Didn't know the new clamps were out, good to know. Are new clamps coming with the new digi's now?

Clamps are an add-on option or accessory that can be added.

As of now, they are still not available for the AK-900. There is an upgraded sensor for the AK, but not a clamp, yet.

How do you calibrate your digital gauge?

How do you calibrate your digital gauge?

Unlike cheap analogs, a quality digital set doesn't require frequent calibrations.

There is a local zero function to account for variations in atmospheric pressure, but it really isn't calibration.


How do you calibrate your analogs?

Proper calibration requires more than just zeroing a gauge.

When the down pour is coming I pull the plastic bag off a media filter and use it to protect manifold and meter.

How do you calibrate your digital gauge?

The Fieldpiece ones have a calibration function that works pretty much the same as checking the calibration of any gauge against the saturated pressure of a refrigerant at a stable temperature.

Digi-Cool and Testo gauges are not truly field calibratable, but you can still check the calibration of them.

You can kind of "calibrate" a Digi-Cool by pulling a very deep vacuum on the manifold, switching over to displaying absolute pressure, and zeroing the instrument.
It isn't really calibrating the instrument, but it is a handy trick for people at higher altitudes.

The only time my 6 year old, much abused, Digi-Cool BTD-1000 failed a calibration check on one of the sensors, I replaced the sensor and it was spot on. The calibration data is stored on the sensor.

My first generation Testo 523 is still in calibration too.

Yes of course water won't enter the system with gauges attached
It's during the attachment process take off the caps with wet hands water dripping from your rain suit from the unit itself water splashing onto the ports that's how but i have replaced compressors in the rain you gotta do what you gotta do
i have a ten by ten canopy for rainy days and balls hot days but realistically if i wasn't gonna be long i wouldn't carry that thing up on a roof

But if you're worried about your digital gauges don't use them
that's how to protect them from the rain

Road apples. Oil residue on the ports repeals water. And I have been wiping off the inside of caps even when it it's dry out side.
