1.Basic Parameters

The basic parameters are shown as table 1

Table 1

2Technique Requirements

2.1environmental conditions

2.1.1 environmental temperature 15—25℃

2.1.2 relative humidity ≤85%RH

2.1.3 power 220V±10%, 48-62Hz

2.2basic tolerance

The basic tolerance of the measurement is shown as table 2

R X：reading of the measurement R m：maximum value of the range

2.3Accurate class and maximum tolerance

shown as table 3.

The accurate class and maximum tolerance is

The rated output currents of the measurement are shown as table 4.

2.5Two way current measurement

Once the thermoelectric voltage of the circuit is removed the difference of the result between the positive current measurement and negative current measurement is less than the half of the basic tolerance.

2.6 Temperature conversion of the copper wire and aluminum wire

2.6.1 temperature conversion range

environmental temperature input ringing from15℃to26℃with the step of 0.1℃.

2.6.2 properties of temperature conversion

K t = 1/ [1+0.004( t-20 )] = 250 / (230 + t )

t: environmental temperature ℃.

2.6.3 readout of the meter: R X= R20 = K t*R t

R20：resistance at 20℃; R t：resistance at t℃

2.7Insulation resistance

Insulation resistance is more than 20 MΩbetween power input leads and outside sell of the meter.

2.8Insulation strength

Insulation strength is 50Hz at 1500V (1 minute) between power input leads and outside sell of the meter.

3Operation methods

3.1 Introduction of panel function

Of which:

(1)liquid crystal display (8) measurement state choice switch

(2)range choice switch (9) current output terminal “C1”

(3)function choice switch (10) voltage input terminal “P1,P2”

(4)power switch (11) current output terminal “C2”

(5)zero check and balance knob (12) environmental temperature input switch

(6)reading hold switch (15-26℃,step 1℃)

(7) current direction choice switch (13) environmental temperature input switch

(0.0-1.1℃,step 0.1℃)

（14）temperature conversion switch

Note: The meter has 12 ranges, but the range choice switch (2) has only 6 positions for turning. When the measurement state choice switch (8) is turned to the “normal current” (normal current measurement) position, the screen displays“ THI”, the 6 ranges witch on the upper position of the panel (printed in blue) is effective; and when the switch (8) is turned to the “low current” (low current measurement) position, the screen displays“ TLO”, the 6 ranges witch on the lower position of the panel (printed in black) is effective. The screen displays the maximum value of range ( 2、20 、200 or 2000 ) and the unit of the resistance (Ω、mΩ、μΩ)when measuring
