What is a Flexitest switch?
What is a Flexitest switch?
The FT-1 Flexitest switch is designed and manufactured to allow quick and easy multi-circuit testing of switchboard relays, meters, and instruments by any conventional system. Scope. Multi-circuit testing of switchboard relays, meters, and instruments.
What is a current test jack?
This Test Plug is typically used to connect devices measuring the currents and voltages being applied to the switchboard relays, meters and instruments without interrupting or short-circuiting the circuit. Only current test switches with a current jack must be opened before inserting the Series Test Plug.
What is Flexitest?
Introduced in 1980 and with redesigned evaluation maps published in 1986, Flexitest consists of the assessment of mobility with the use of a scale from 0 to 4. By adding the individual results of the 20 joint movements assessed, it is possible to obtain a global score called Flexindex.
What is test switch?
Test switches are designed and manufactured to allow quick and easy multi-circuit testing of switchboard relays, meters and instruments by any conventional system.
What is Flexitest 13?
The Flexitest(1,2,11-13) is a method for measurement and evaluation of the passive mobil- ity of 20 joint movements (see description of movements in table 1) in which each movement is quantified in an ordinal scale from 0 to 4, involving these two important aspects as allowing concur- rently the attainment of a global …
What does F mean on lab results?
The p value is a probability, while the f ratio is a test statistic, calculated as: F value = variance of the group means (Mean Square Between) / mean of the within group variances (Mean Squared Error)
Why CT polarity is important?
It is important to avoid continuous contact, which will short circuit the battery. If polarity is correct, the momentary contact causes a small deflection in the analog meter in the positive direction. If the deflection is negative the polarity of the current transformer is reversed.
How do you use a test switch?
Single-pole switch: Clip the wire of a continuity tester to one of the screw terminals, and touch the other terminal with the tester probe. Turn the switch lever on and off. The tester should light up when the switch lever is in the on position but should not light up when the switch lever is off.
What does flag H mean on lab results?
A numeric result that is greater than the upper end of the reference interval will automatically flag as “H,” and a numeric result that is less than the lower end will automatically flag as “L.” Tests with a numeric result type for which no reference interval is defined in the LIS do not trigger any flags regardless of …
What does C mean on lab results?
White Blood Cell Count (WBC) Urinalysis. Platelet Count. Alkaline Phosphatase (ALP) C-Reactive Protein (CRP)
Why CT S2 is earthed?
To prevent the secondary circuits from attaining dangerously high potential to ground, these circuits have to be grounded. Connect either the S1 terminal or the S2 terminal to ground.
How can you tell if a switch is bad?
Touch each tester probe to one of the screw terminals, then turn the switch lever on and off. If the switch is good, the tester will read close to zero when the switch lever is in the on position, indicating that there is perfect continuity (no resistance).
Does flag a mean abnormal?
Flags: for paper results There is often an empty column with marks identifying which rows contain abnormal bloodwork results. The mark may be an asterisk, or an “H” for high or “L” for low or “A” for abnormal.
What does flag a on urine test mean?
This is ‘normal’. Here, the computer has flagged this as an ‘abnormal’ result, because it thinks the value is ‘low’. This is a case of incomplete coding of the lab system. The second example shows a urine drug screen labs results without a ‘reference range’, being displayed in the same style as ‘normal’ bloodwork.
