Wattage 'adds up' regardless of series or parallel wiring.
That test board needs to be made up (or purchased) accordingly and will load up the relevant PSU outputs at which point you will measure the fixed DC values (or waveforms) according to the tests they specify. The resistance totals won't necessarily be connected in series/parallel (so you can't just replace them with 'one' resistor) therefore you have to make the board using the values and wattages specified.
It's not clear whether the wattages shown are 'per resistor' or the total for the series required. I suspect they are the individual values as the single value resistors are shown as the wattage required. Either way, using higher wattage resistors won't do any damage but using lower ones might....
a) TP 10 - Value of 3x3R (3W) of the J11 connector (pin 8)
b) TP 11 - Value of 2x27R (1/2W) of the J13 connector (pin 1)
wondering whether the total resistor's value depends on connecting the resistors in series or in parallel mode. ie, in case a) the true and total value of the resistor could either be 9 Ω (3W) or 1 Ω (9W) while in case b) the resistor's total and true value would be either
54Ω(1/2W) or 13.5 Ω (1W). Same thing applies to the TP 13's resistor which it marks a 2x91 R (2W).
c) TP 17 - in the schematic of the power supply's tool in pin 3 of the J12 connector, the printing of the corresponding resistor cannot be
determined, because it reads something like 14x3R9 (1W) which could mean a total resistance of 54.6 Ω (1W) or less than 0.3 Ω 14W).

Thank you for your reply. At first let me state that I carry at least 45 years in electronics. Indeed it is not clear as to the resistors's values and not as much as for their total wattage values. Meanwhile, the question remains as to the value of the specific TP's resistance values. For example, in the drawing there are resistor values of 900 R. There isn't around a standard value as such, but can easily can be made by two resistors in series. Therefore, and that's what has been puzzled me about, why haven't they stated the total resistance value at the said points instead of writting them down as ie. 2x3 R and not either 9 R or as 1R. Wattage is not the issue here, of course a higher value won't do any harm. I have already assembled a pcb for the tool and have soldered higher wattage resistors on it, but before I put it on the test I asked for a fresh opinion on the matter. Moreover, the puzzling point rests on the resistance value in connector J12 (TP17) where due to blurry printing of the circuit. Is it 14x3R9 as I tend to read or some other value that someone else could read its value better than my eyes can see.
