I have DVM ISO- TECH IDM93N
AC range not working just reads 1499.
DC range reads 1 . on all ranges
DC current not giving correct values compared to another DVM
Resistance range reads 1 . and floating readings
Diode range reads 1.
Both fuses okay.

Have you opened the meter up to inspect the PCB and components?

Do you know which microcontroller is used for that meter?

It may help you in finding a datasheet/schematic to fault find.
