a.
If the UUT displayed voltage is not within ±0.001 mV of the Applied
Voltage, press
until the UUT displayed voltage is within ±0.001
mV, adjusting as close to the Applied Voltage as possible.
b.
If the UUT displayed voltage is too far from nominal,
may not
function as expected. The UUT will typically indicate 8999 or -999 in this
state. To set the active CAL factor to its default value, press the
(1.5s)
arrow buttons simultaneously for 1.5 seconds. Fine
adjustments may still be necessary.
17.
Press UUT
. The display will change to rES1 [2, 3 …] showing the actual
measured value saved in the previous step.
18.
Press UUT
again. This will increment to the next CAL value.
19.
Repeat Steps 12 through 18 for each remaining value in Figure 13 below. For
single channel UUTs, omit Channel 2 values.
a.
For two channel UUTs using the single-ended Copper Mini-TC Cable,
disconnect the cable from the UUT Channel 1 input, and reconnect the
cable to the Channel 2 input after completing CAL4 in Figure 13 below.
Repeat Step 11.

Connect one end of the Type E
Thermocouple Cable to the UUT Channel 1 input.
a.
For two channel UUTs using the Split Thermocouple Cable, connect the
miniature thermocouple connector of one leg to the UUT Channel 1
input, and the miniature thermocouple connector of the other leg to the
Channel 2 input.

If substituting another thermocouple type, use the appropriate Thermocouple Cable for the
selected thermocouple type.
