TROUBLE SHOOTING
If the meter locks on a particular display, unplug and plug in again the meter to unlock the display.
A total reset defaults all scaling values to zero. To perform this reset,
Factory preset values for Current, Voltage and millivolt, respectively, can be programmed by simply re- apply power with either ^v, RATE or TARE key pressed in. Respective default values are for CURRENT, VOLTAGE and MILLIVOLT inputs are:
Factory default settings for voltage, current and millivolt:
| CURRENT | VOLTAGE | MILLIVOLT |
PARAMETER | INPUT | INPUT | INPUT |
HIGH SCALE | 20.000 | 10.000 | 100.00 |
LOW SCALE | 0.000 | 0.000 | 0.000 |
OFFSET | 0.00 | 0.00 | 0.00 |
TARE | 0.000 | 0.000 | 0.000 |
LIMITS | 1.000 | 1.000 | 1.000 |
