Basic version of the calibrator offers continuously adjustable resistance decade LVR, based on resistance
simulation using electronic circuits. The function is designed for calibration of standard resistance
function of various multimeters which use low level signals. The mode is signed VARIABLE. FIXED
mode offers set of fixed decadic resistors with higher accuracy.
Calibrator can be equipped with high resistance option HVR, designed for calibration of insulation
meters, megaohmmeters.
Push RESISTANCE function key to select resistance function.
Low resistance decade can be used in two-wire or four-wire connection. Two-wire connection uses
output terminals labelled HI and LO. Four-wire connection uses terminals HI and LO as “power”
terminals and +I and -I as “sense“ terminals.
Note: four-wire method of connection offers lower uncertainty of calibration especially for low
resistance values due to by the principle excluded test lead resistance influence.
Low resistance mode function is based on electronic simulator of resistance. It has limited working
conditions. Maximum test voltage is 20 V. See specification for test voltage and test current limitations.
If HVR High resistance decade option is installed push RESISTANCE function key repeatedly until
RESITANCE LVR mode is selected. Push MODE soft key to display list of modes. Select Variable and
confirm with ENTER. Connect the ohmmeter (multimeter) to the calibrator as shown below.
1. Select appropriate function and range on the ohmmeter (multimeter)
2. Set requested mode of connection either two-wire or four-wire. Use WIRE soft key to switch
between both modes. Set up requested resistance value.
3. Switch output terminals on by pushing key OPER.
4. Push STBY key to switch output off.
