Resistance threshold selection
The unit includes two comparison thresholds making possible to check if the specimen under test
is good or bad.
These thresholds can be
a resistance or a voltage
(according to the requirements of standard
EN60204-1
).
The H LIMIT defines the maximum resistance value which is allowed for the specimen under test.
The L LIMIT defines the minimum resistance value in Ohms or Volts that can be reached by the
specimen under test.
A specimen is good (PASS) if the resistance is under H LIMIT and over L LIMIT, otherwise the
specimen is declared bad (FAIL).
Those thresholds are adjustable from 0 to 1500m
or 0.01V to 12.0V.
Move the reverse video line in front of the H LIMIT line.
Press on the RIGHT arrow or ENTER key.
Display shows :
Fig 9.5
Select the number to be modified by moving the cursor with the RIGHT/LEFT arrow keys.
Increase or decrease the value with respectively the UP and the DOWN arrow keys (0 1 2 3 4 5
6 7 8 9. 0 1 2 ...).
Enter the threshold with the ENTER key. Warning, the H LIMIT must always be higher than the
L LIMIT, otherwise an error message is displayed :
H LIMIT < L LIMIT
To set the L LIMIT value, proceed the same way as for the H LIMIT. Warning, the L LIMIT must
always be lower than the H LIMIT, otherwise an error message is displayed :
L LIMIT > H LIMIT
If you whish to modify the unity (for instance switch from Ohm to Volt), use the right arrow as
much times as you need to place the unity on reverse video. Then change it with UP and
DOWN arrows.
Warning : when changing the unity (ohm to volt), you must enter again the two thresholds.
