TEA package arrived today.
Should have six items in it but the packking is not looking good. Even Hermes thought it needed more tape

Two heavy units. a resistve load bank and a AC power supply with no packing between them

At least the meters were in a cheap ply and thin aluminium case.
The powersupply is an odd one basically a 200VA 15V transformer in a box with some werd switching and binding posts. I had not realised it was part of the bundle so total bonus.
The loadbank had two toggle switches broken. How the meter survived I've no idea. It has 6 power resistors switched by relays. They are fan cooled. The control behind the select toggle switch is complex. There is a bicolour LED by each toggle to indicate the state and then a bunch of logic to light up "maximum votage" (power) LEDs.
It is reallly well built and everything is crammed in. The 6 toggle switches are fixed to a sub panel and once the front nuts are removed they come out as a block so easy to change out the broken ones. all but 1 are 4PCO presumbly 3 of the poles are used for the LEDs.
Each resistor has 2 relays for 12 total. There is a mains transformer in there too.
Once the switches were changed it all works

Next on the list was the Fluke. It's a basic 8022B. Stuck a battery in it and LCD is fine but no response to volts and ewird readings on Ohms. Checked input resistance and it's open circuit

Must be either an input resistor or a switch fault.
Quick check showed the 1k and 100k resistors on the +Ve terminal (R1 & 2) are faulty. The 1k is open and the 100k is 200k. Replaced those and the battery snap (corroded) and it works

Photo shows it next to to a 89IV and its pretty good. Broke out the 6.5 digit and it's the 89 that is out by about 9mV. The 8922B was spot on without any adjustment. Can't beat an (old) Fluke

I think I'll just flip the Metrotest stuff I got an all in one installation tester already.
Dispite the issues it's still a bargain for <£30 shipped I'm sure the £3.20 postage cost was a mistake
