Notes [1] For ac measurements, resolution is fixed at 6½ digits. The resolution
[2] For frequency measurements, the Meter uses one range for all inputs
[3] For period measurements, the Meter uses one range for all inputs
[4] The range and resolution are fixed for temperature measurements.
[5] The range and resolution are fixed for diode test: 10 Vdc range and 5½
[6] The range and resolution are fixed for continuity tests: 1 kΩ range and
[7] DC measurement voltage divided by dc reference voltage. For dc ratio,
For best results in RATIO, the two input commons must be shorted at the
Meter terminals. The analog filter (AFLTR) should be off.

between 3 Hz, and 300 kHz. With no input signal applied, frequency
measurements return zero.
between 0.33 seconds, and 3.3 µsec. With no input signal applied,
period measurements return zero.
However, placing PT100_385 or PT100_392 into the range field will
set the RTD type. Placing CUST1 into the range field will cause the
Meter to use the values set into the R
digits. When set to ON, the low current parameter sets the diode test
current to 0.1 mA. When OFF, the current is 1 mA. When set to ON,
the high voltage parameter sets the diode test voltage to 10 volts. When
OFF, the voltage is 5 volts. To specify a diode test voltage, you must
also include ON or OFF for the low current parameter.

connect the reference HI/LO to the HI/LO sense terminals of the Meter
and the measurement voltage to the HI/LO input terminals of the
Meter. Note the specified measurement range applies to the input
terminals only.
