will be influenced by the temperature measurement result.
Therefore, if you only measure the resistance value please be sure TEMP.: (F3) is OFF as
well as panel display is RX.
2. Parameters settings are as following descriptions:
DRIVE:
Test mode setting, please see section 4.5 Reference Data for Operation. There are
PULSE+/-, PULSE+, PULSE-, DC+, DC-, DC+ NA, STBY six modes. The default value is
PULSE+/-. Press [F1] key to switch directly in sequence.
PULSE+/-: It offers positive/negative square wave levels for switching SOURCE signal of
+2V0V -2V0V DC.
PULSE+ : It offers positive square wave level for switching SOURCE signal of +2V
0V
DC.
PULSE- : It offers negative square wave level for switching SOURCE signal of -2V
0V
DC.
DC+ : It offers SOURCE signal of DC+2V level.
DC - : It offers SOURCE signal of DC-2V level.
DC+ NA : It offers SOURCE signal of DC+2V level (for speed acceleration). For circuit
offset error during process doesn’t run measurement.
STBY : It is under STANDBY status.
DRY:
DRY CIRCUIT is with OFF and ON two modes. The default value is OFF. By pressing [F2]
to switch directly. When DRY = ON, the test terminal on front panel provides 20mV of
maximum test voltage, it can prevent DUT from the danger of burning.
TRIG.:
Trigger mode. There are INTernal, EXTernal, MANual and SMT (SMART TRIG) four
modes. By pressing [F3] to switch directly, the default value is INT.
RANGE:
Range setting. A represents Auto (Auto skip range), H represents Hold (Manual fixed
range). Press [F1] key, then press [], [] direction keys to move the cursor to range
number, and press [], [] for switching. There are 2MΩ, 200KΩ, 20KΩ, 2KΩ, 200Ω,
20Ω, 2Ω, 200mΩ and 20mΩ nine ranges. (When DRY CIRCUIT = ON, 20Ω, 2Ω and
200mΩ ranges only)
SPEED:
Measuring speed setting. MAX means maximum speed, V.FAST means very fast, FAST
means high speed, MEDIUM means middle speed, SLOW means low speed, the lower of
speed, the more stable in stability. Press [F2] to switch measuring speed directly. Factory
default value is FAST.
ZERO:
Zero setting. Can deduct residual impedance from test fixture or test cable. Press [F3]
directly to select OFF or ON. Factory default value is OFF.
COMPARE:
High/low limit compare setting. There are OFF, ON, ON-⊿%, ON-⊿ four selections.
Press [F1] for switching. This parameter is for high/low limit and central value setting under
MAIN INDEX menu.
